Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647086, here are decompositions:

23 + 8647063 = 8647086
43 + 8647043 = 8647086
59 + 8647027 = 8647086
79 + 8647007 = 8647086
137 + 8646949 = 8647086
139 + 8646947 = 8647086
157 + 8646929 = 8647086
197 + 8646889 = 8647086

Showing the first eight; more decompositions exist.
