Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637568, here are decompositions:

41 + 8637527 = 8637568
47 + 8637521 = 8637568
59 + 8637509 = 8637568
101 + 8637467 = 8637568
227 + 8637341 = 8637568
257 + 8637311 = 8637568
311 + 8637257 = 8637568
389 + 8637179 = 8637568

Showing the first eight; more decompositions exist.
