Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723812, here are decompositions:

5 + 8723807 = 8723812
23 + 8723789 = 8723812
173 + 8723639 = 8723812
281 + 8723531 = 8723812
353 + 8723459 = 8723812
389 + 8723423 = 8723812
491 + 8723321 = 8723812
509 + 8723303 = 8723812

Showing the first eight; more decompositions exist.
