Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637998, here are decompositions:

7 + 8637991 = 8637998
151 + 8637847 = 8637998
211 + 8637787 = 8637998
331 + 8637667 = 8637998
379 + 8637619 = 8637998
547 + 8637451 = 8637998
571 + 8637427 = 8637998
619 + 8637379 = 8637998

Showing the first eight; more decompositions exist.
