Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749812, here are decompositions:

23 + 8749789 = 8749812
41 + 8749771 = 8749812
59 + 8749753 = 8749812
61 + 8749751 = 8749812
79 + 8749733 = 8749812
199 + 8749613 = 8749812
223 + 8749589 = 8749812
233 + 8749579 = 8749812

Showing the first eight; more decompositions exist.
