Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738618, here are decompositions:

37 + 8738581 = 8738618
79 + 8738539 = 8738618
127 + 8738491 = 8738618
181 + 8738437 = 8738618
211 + 8738407 = 8738618
241 + 8738377 = 8738618
337 + 8738281 = 8738618
379 + 8738239 = 8738618

Showing the first eight; more decompositions exist.
