Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672564, here are decompositions:

3 + 8672561 = 8672564
13 + 8672551 = 8672564
37 + 8672527 = 8672564
157 + 8672407 = 8672564
211 + 8672353 = 8672564
463 + 8672101 = 8672564
577 + 8671987 = 8672564
727 + 8671837 = 8672564

Showing the first eight; more decompositions exist.
