Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702218, here are decompositions:

11 + 8702207 = 8702218
29 + 8702189 = 8702218
59 + 8702159 = 8702218
167 + 8702051 = 8702218
227 + 8701991 = 8702218
257 + 8701961 = 8702218
269 + 8701949 = 8702218
311 + 8701907 = 8702218

Showing the first eight; more decompositions exist.
