Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042630, here are decompositions:

11 + 1042619 = 1042630
23 + 1042607 = 1042630
47 + 1042583 = 1042630
53 + 1042577 = 1042630
59 + 1042571 = 1042630
101 + 1042529 = 1042630
107 + 1042523 = 1042630
179 + 1042451 = 1042630

Showing the first eight; more decompositions exist.
