Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717618, here are decompositions:

61 + 8717557 = 8717618
67 + 8717551 = 8717618
97 + 8717521 = 8717618
109 + 8717509 = 8717618
127 + 8717491 = 8717618
229 + 8717389 = 8717618
277 + 8717341 = 8717618
331 + 8717287 = 8717618

Showing the first eight; more decompositions exist.
