Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647166, here are decompositions:

37 + 8647129 = 8647166
43 + 8647123 = 8647166
103 + 8647063 = 8647166
139 + 8647027 = 8647166
223 + 8646943 = 8647166
277 + 8646889 = 8647166
313 + 8646853 = 8647166
349 + 8646817 = 8647166

Showing the first eight; more decompositions exist.
