Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668718, here are decompositions:

7 + 8668711 = 8668718
31 + 8668687 = 8668718
109 + 8668609 = 8668718
199 + 8668519 = 8668718
229 + 8668489 = 8668718
337 + 8668381 = 8668718
349 + 8668369 = 8668718
439 + 8668279 = 8668718

Showing the first eight; more decompositions exist.
