Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042668, here are decompositions:

37 + 1042631 = 1042668
59 + 1042609 = 1042668
61 + 1042607 = 1042668
71 + 1042597 = 1042668
97 + 1042571 = 1042668
139 + 1042529 = 1042668
149 + 1042519 = 1042668
181 + 1042487 = 1042668

Showing the first eight; more decompositions exist.
