Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629618, here are decompositions:

5 + 8629613 = 8629618
269 + 8629349 = 8629618
419 + 8629199 = 8629618
449 + 8629169 = 8629618
461 + 8629157 = 8629618
479 + 8629139 = 8629618
509 + 8629109 = 8629618
719 + 8628899 = 8629618

Showing the first eight; more decompositions exist.
