Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749672, here are decompositions:

3 + 8749669 = 8749672
59 + 8749613 = 8749672
83 + 8749589 = 8749672
101 + 8749571 = 8749672
233 + 8749439 = 8749672
251 + 8749421 = 8749672
443 + 8749229 = 8749672
509 + 8749163 = 8749672

Showing the first eight; more decompositions exist.
