Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617146, here are decompositions:

17 + 8617129 = 8617146
37 + 8617109 = 8617146
73 + 8617073 = 8617146
149 + 8616997 = 8617146
157 + 8616989 = 8617146
199 + 8616947 = 8617146
227 + 8616919 = 8617146
229 + 8616917 = 8617146

Showing the first eight; more decompositions exist.
