Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637868, here are decompositions:

47 + 8637821 = 8637868
89 + 8637779 = 8637868
167 + 8637701 = 8637868
227 + 8637641 = 8637868
251 + 8637617 = 8637868
257 + 8637611 = 8637868
347 + 8637521 = 8637868
359 + 8637509 = 8637868

Showing the first eight; more decompositions exist.
