Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723564, here are decompositions:

13 + 8723551 = 8723564
43 + 8723521 = 8723564
67 + 8723497 = 8723564
127 + 8723437 = 8723564
211 + 8723353 = 8723564
373 + 8723191 = 8723564
457 + 8723107 = 8723564
523 + 8723041 = 8723564

Showing the first eight; more decompositions exist.
