Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617188, here are decompositions:

11 + 8617177 = 8617188
17 + 8617171 = 8617188
59 + 8617129 = 8617188
79 + 8617109 = 8617188
191 + 8616997 = 8617188
197 + 8616991 = 8617188
199 + 8616989 = 8617188
241 + 8616947 = 8617188

Showing the first eight; more decompositions exist.
