Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618018, here are decompositions:

181 + 8617837 = 8618018
337 + 8617681 = 8618018
457 + 8617561 = 8618018
499 + 8617519 = 8618018
571 + 8617447 = 8618018
601 + 8617417 = 8618018
691 + 8617327 = 8618018
727 + 8617291 = 8618018

Showing the first eight; more decompositions exist.
