Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678320, here are decompositions:

83 + 8678237 = 8678320
107 + 8678213 = 8678320
173 + 8678147 = 8678320
179 + 8678141 = 8678320
191 + 8678129 = 8678320
227 + 8678093 = 8678320
239 + 8678081 = 8678320
251 + 8678069 = 8678320

Showing the first eight; more decompositions exist.
