Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612748, here are decompositions:

5 + 8612743 = 8612748
17 + 8612731 = 8612748
19 + 8612729 = 8612748
37 + 8612711 = 8612748
41 + 8612707 = 8612748
47 + 8612701 = 8612748
59 + 8612689 = 8612748
61 + 8612687 = 8612748

Showing the first eight; more decompositions exist.
