Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618164, here are decompositions:

17 + 8618147 = 8618164
101 + 8618063 = 8618164
131 + 8618033 = 8618164
173 + 8617991 = 8618164
293 + 8617871 = 8618164
461 + 8617703 = 8618164
617 + 8617547 = 8618164
641 + 8617523 = 8618164

Showing the first eight; more decompositions exist.
