Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707680, here are decompositions:

11 + 8707669 = 8707680
19 + 8707661 = 8707680
29 + 8707651 = 8707680
31 + 8707649 = 8707680
73 + 8707607 = 8707680
89 + 8707591 = 8707680
101 + 8707579 = 8707680
251 + 8707429 = 8707680

Showing the first eight; more decompositions exist.
