Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723708, here are decompositions:

31 + 8723677 = 8723708
139 + 8723569 = 8723708
157 + 8723551 = 8723708
211 + 8723497 = 8723708
229 + 8723479 = 8723708
271 + 8723437 = 8723708
349 + 8723359 = 8723708
397 + 8723311 = 8723708

Showing the first eight; more decompositions exist.
