Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678278, here are decompositions:

41 + 8678237 = 8678278
131 + 8678147 = 8678278
137 + 8678141 = 8678278
149 + 8678129 = 8678278
197 + 8678081 = 8678278
227 + 8678051 = 8678278
239 + 8678039 = 8678278
251 + 8678027 = 8678278

Showing the first eight; more decompositions exist.
