Yes.
Two possible examples are
(N2−3N+1, N2−N+1, −3N2+3N−1, N2+N−1)
and
(N3−N2+1, N3−3N2+2N−1, −N3+N2−2N+1, −N3+N2+2N−1),
where N is an integer greater than 106.
First solution. For example, the numbers
x=N2−3N+1, y=N2−N+1, z=−3N2+3N−1, t=N2+N−1,
where N is a natural number greater than a million.
It is easy to see that these numbers are also greater than a million in absolute value and pairwise distinct. Their pairwise sums are
x+y=2(N−1)2, x+z=−2N2, y+z=−2N(N−1), z+t=−2(N−1)2, y+t=2N2, x+t=2N(N−1),
with the products
(x+y)(x+z)=(y+t)(z+t)=(x+t)(y+z)=−4N2(N−1)2.
It remains to check that the numbers x,y,z,t are coprime as a set. If they have a common natural divisor d, then d also divides x+y=2(N−1)2 and y+t=2N2; thus, d≤gcd(2N2,2(N−1)2)=2. The case d=2 is impossible since y=N(N−1)+1 is odd. Therefore, d=1, as required.
Second solution. Another example is
x=N3−N2+1, y=N3−3N2+2N−1, z=−N3+N2−2N+1, t=−N3+N2+2N−1,
where N is a natural number greater than a million. Again, these numbers are greater than a million in absolute value and pairwise distinct. Their pairwise sums are
x+y=2N(N−1)2, x+z=−2(N−1), y+z=−2N2, z+t=−2N2(N−1), y+t=−2(N−1)2, x+t=2N,
and they can be grouped into three pairs with equal products:
(x+y)(x+t)=(x+z)(z+t)=(y+z)(y+t)=4N2(N−1)2.
The coprimality of x,y,z,t is checked analogously to the previous solution.
