Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732688, here are decompositions:

11 + 8732677 = 8732688
47 + 8732641 = 8732688
61 + 8732627 = 8732688
89 + 8732599 = 8732688
137 + 8732551 = 8732688
199 + 8732489 = 8732688
227 + 8732461 = 8732688
241 + 8732447 = 8732688

Showing the first eight; more decompositions exist.
