Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042636, here are decompositions:

3 + 1042633 = 1042636
5 + 1042631 = 1042636
17 + 1042619 = 1042636
29 + 1042607 = 1042636
53 + 1042583 = 1042636
59 + 1042577 = 1042636
107 + 1042529 = 1042636
113 + 1042523 = 1042636

Showing the first eight; more decompositions exist.
