Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678290, here are decompositions:

53 + 8678237 = 8678290
149 + 8678141 = 8678290
197 + 8678093 = 8678290
227 + 8678063 = 8678290
233 + 8678057 = 8678290
239 + 8678051 = 8678290
251 + 8678039 = 8678290
263 + 8678027 = 8678290

Showing the first eight; more decompositions exist.
