Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706440, here are decompositions:

37 + 8706403 = 8706440
73 + 8706367 = 8706440
79 + 8706361 = 8706440
103 + 8706337 = 8706440
151 + 8706289 = 8706440
157 + 8706283 = 8706440
163 + 8706277 = 8706440
199 + 8706241 = 8706440

Showing the first eight; more decompositions exist.
