Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617770, here are decompositions:

17 + 8617753 = 8617770
67 + 8617703 = 8617770
71 + 8617699 = 8617770
89 + 8617681 = 8617770
223 + 8617547 = 8617770
251 + 8617519 = 8617770
257 + 8617513 = 8617770
331 + 8617439 = 8617770

Showing the first eight; more decompositions exist.
