Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637578, here are decompositions:

97 + 8637481 = 8637578
127 + 8637451 = 8637578
151 + 8637427 = 8637578
199 + 8637379 = 8637578
241 + 8637337 = 8637578
277 + 8637301 = 8637578
331 + 8637247 = 8637578
487 + 8637091 = 8637578

Showing the first eight; more decompositions exist.
