Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617992, here are decompositions:

43 + 8617949 = 8617992
59 + 8617933 = 8617992
193 + 8617799 = 8617992
223 + 8617769 = 8617992
239 + 8617753 = 8617992
293 + 8617699 = 8617992
311 + 8617681 = 8617992
431 + 8617561 = 8617992

Showing the first eight; more decompositions exist.
