Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637988, here are decompositions:

59 + 8637929 = 8637988
167 + 8637821 = 8637988
197 + 8637791 = 8637988
239 + 8637749 = 8637988
347 + 8637641 = 8637988
461 + 8637527 = 8637988
467 + 8637521 = 8637988
479 + 8637509 = 8637988

Showing the first eight; more decompositions exist.
