Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617788, here are decompositions:

19 + 8617769 = 8617788
89 + 8617699 = 8617788
107 + 8617681 = 8617788
227 + 8617561 = 8617788
239 + 8617549 = 8617788
241 + 8617547 = 8617788
269 + 8617519 = 8617788
349 + 8617439 = 8617788

Showing the first eight; more decompositions exist.
