Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723678, here are decompositions:

109 + 8723569 = 8723678
127 + 8723551 = 8723678
157 + 8723521 = 8723678
181 + 8723497 = 8723678
199 + 8723479 = 8723678
241 + 8723437 = 8723678
331 + 8723347 = 8723678
367 + 8723311 = 8723678

Showing the first eight; more decompositions exist.
