Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637926, here are decompositions:

79 + 8637847 = 8637926
97 + 8637829 = 8637926
139 + 8637787 = 8637926
229 + 8637697 = 8637926
307 + 8637619 = 8637926
433 + 8637493 = 8637926
499 + 8637427 = 8637926
547 + 8637379 = 8637926

Showing the first eight; more decompositions exist.
