Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650440, here are decompositions:

11 + 8650429 = 8650440
17 + 8650423 = 8650440
31 + 8650409 = 8650440
79 + 8650361 = 8650440
131 + 8650309 = 8650440
157 + 8650283 = 8650440
181 + 8650259 = 8650440
223 + 8650217 = 8650440

Showing the first eight; more decompositions exist.
