Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723516, here are decompositions:

19 + 8723497 = 8723516
37 + 8723479 = 8723516
79 + 8723437 = 8723516
97 + 8723419 = 8723516
157 + 8723359 = 8723516
163 + 8723353 = 8723516
199 + 8723317 = 8723516
313 + 8723203 = 8723516

Showing the first eight; more decompositions exist.
