Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042626, here are decompositions:

7 + 1042619 = 1042626
17 + 1042609 = 1042626
19 + 1042607 = 1042626
29 + 1042597 = 1042626
43 + 1042583 = 1042626
97 + 1042529 = 1042626
103 + 1042523 = 1042626
107 + 1042519 = 1042626

Showing the first eight; more decompositions exist.
