Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618128, here are decompositions:

41 + 8618087 = 8618128
107 + 8618021 = 8618128
137 + 8617991 = 8618128
179 + 8617949 = 8618128
251 + 8617877 = 8618128
257 + 8617871 = 8618128
359 + 8617769 = 8618128
809 + 8617319 = 8618128

Showing the first eight; more decompositions exist.
