Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672584, here are decompositions:

23 + 8672561 = 8672584
71 + 8672513 = 8672584
83 + 8672501 = 8672584
101 + 8672483 = 8672584
113 + 8672471 = 8672584
197 + 8672387 = 8672584
251 + 8672333 = 8672584
311 + 8672273 = 8672584

Showing the first eight; more decompositions exist.
