Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674156, here are decompositions:

47 + 8674109 = 8674156
107 + 8674049 = 8674156
167 + 8673989 = 8674156
233 + 8673923 = 8674156
317 + 8673839 = 8674156
479 + 8673677 = 8674156
563 + 8673593 = 8674156
587 + 8673569 = 8674156

Showing the first eight; more decompositions exist.
