Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042650, here are decompositions:

17 + 1042633 = 1042650
19 + 1042631 = 1042650
31 + 1042619 = 1042650
41 + 1042609 = 1042650
43 + 1042607 = 1042650
53 + 1042597 = 1042650
67 + 1042583 = 1042650
73 + 1042577 = 1042650

Showing the first eight; more decompositions exist.
