Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672800, here are decompositions:

11 + 8672789 = 8672800
113 + 8672687 = 8672800
179 + 8672621 = 8672800
239 + 8672561 = 8672800
281 + 8672519 = 8672800
317 + 8672483 = 8672800
359 + 8672441 = 8672800
419 + 8672381 = 8672800

Showing the first eight; more decompositions exist.
