Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723510, here are decompositions:

13 + 8723497 = 8723510
31 + 8723479 = 8723510
73 + 8723437 = 8723510
151 + 8723359 = 8723510
157 + 8723353 = 8723510
163 + 8723347 = 8723510
193 + 8723317 = 8723510
199 + 8723311 = 8723510

Showing the first eight; more decompositions exist.
