Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723764, here are decompositions:

233 + 8723531 = 8723764
281 + 8723483 = 8723764
443 + 8723321 = 8723764
461 + 8723303 = 8723764
521 + 8723243 = 8723764
641 + 8723123 = 8723764
683 + 8723081 = 8723764
701 + 8723063 = 8723764

Showing the first eight; more decompositions exist.
