Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637724, here are decompositions:

23 + 8637701 = 8637724
83 + 8637641 = 8637724
107 + 8637617 = 8637724
113 + 8637611 = 8637724
197 + 8637527 = 8637724
233 + 8637491 = 8637724
257 + 8637467 = 8637724
383 + 8637341 = 8637724

Showing the first eight; more decompositions exist.
