Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637844, here are decompositions:

23 + 8637821 = 8637844
53 + 8637791 = 8637844
227 + 8637617 = 8637844
233 + 8637611 = 8637844
317 + 8637527 = 8637844
353 + 8637491 = 8637844
503 + 8637341 = 8637844
521 + 8637323 = 8637844

Showing the first eight; more decompositions exist.
