Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618176, here are decompositions:

3 + 8618173 = 8618176
29 + 8618147 = 8618176
89 + 8618087 = 8618176
113 + 8618063 = 8618176
227 + 8617949 = 8618176
233 + 8617943 = 8618176
353 + 8617823 = 8618176
389 + 8617787 = 8618176

Showing the first eight; more decompositions exist.
