Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747812, here are decompositions:

5 + 8747807 = 8747812
23 + 8747789 = 8747812
53 + 8747759 = 8747812
89 + 8747723 = 8747812
233 + 8747579 = 8747812
239 + 8747573 = 8747812
251 + 8747561 = 8747812
389 + 8747423 = 8747812

Showing the first eight; more decompositions exist.
