Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687730, here are decompositions:

17 + 8687713 = 8687730
31 + 8687699 = 8687730
43 + 8687687 = 8687730
59 + 8687671 = 8687730
61 + 8687669 = 8687730
71 + 8687659 = 8687730
89 + 8687641 = 8687730
127 + 8687603 = 8687730

Showing the first eight; more decompositions exist.
