Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706518, here are decompositions:

61 + 8706457 = 8706518
151 + 8706367 = 8706518
157 + 8706361 = 8706518
181 + 8706337 = 8706518
229 + 8706289 = 8706518
241 + 8706277 = 8706518
277 + 8706241 = 8706518
349 + 8706169 = 8706518

Showing the first eight; more decompositions exist.
