Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668618, here are decompositions:

5 + 8668613 = 8668618
41 + 8668577 = 8668618
47 + 8668571 = 8668618
71 + 8668547 = 8668618
197 + 8668421 = 8668618
239 + 8668379 = 8668618
251 + 8668367 = 8668618
269 + 8668349 = 8668618

Showing the first eight; more decompositions exist.
