Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618188, here are decompositions:

41 + 8618147 = 8618188
101 + 8618087 = 8618188
167 + 8618021 = 8618188
197 + 8617991 = 8618188
239 + 8617949 = 8618188
311 + 8617877 = 8618188
317 + 8617871 = 8618188
389 + 8617799 = 8618188

Showing the first eight; more decompositions exist.
