Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623278, here are decompositions:

17 + 8623261 = 8623278
29 + 8623249 = 8623278
31 + 8623247 = 8623278
137 + 8623141 = 8623278
197 + 8623081 = 8623278
211 + 8623067 = 8623278
227 + 8623051 = 8623278
239 + 8623039 = 8623278

Showing the first eight; more decompositions exist.
