Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647262, here are decompositions:

31 + 8647231 = 8647262
79 + 8647183 = 8647262
139 + 8647123 = 8647262
199 + 8647063 = 8647262
241 + 8647021 = 8647262
313 + 8646949 = 8647262
373 + 8646889 = 8647262
409 + 8646853 = 8647262

Showing the first eight; more decompositions exist.
