Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617228, here are decompositions:

17 + 8617211 = 8617228
41 + 8617187 = 8617228
131 + 8617097 = 8617228
227 + 8617001 = 8617228
239 + 8616989 = 8617228
281 + 8616947 = 8617228
311 + 8616917 = 8617228
317 + 8616911 = 8617228

Showing the first eight; more decompositions exist.
