Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660618, here are decompositions:

7 + 8660611 = 8660618
79 + 8660539 = 8660618
151 + 8660467 = 8660618
157 + 8660461 = 8660618
181 + 8660437 = 8660618
199 + 8660419 = 8660618
331 + 8660287 = 8660618
349 + 8660269 = 8660618

Showing the first eight; more decompositions exist.
