Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637512, here are decompositions:

3 + 8637509 = 8637512
19 + 8637493 = 8637512
31 + 8637481 = 8637512
61 + 8637451 = 8637512
139 + 8637373 = 8637512
193 + 8637319 = 8637512
211 + 8637301 = 8637512
223 + 8637289 = 8637512

Showing the first eight; more decompositions exist.
