Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723086, here are decompositions:

5 + 8723081 = 8723086
23 + 8723063 = 8723086
137 + 8722949 = 8723086
173 + 8722913 = 8723086
227 + 8722859 = 8723086
257 + 8722829 = 8723086
347 + 8722739 = 8723086
443 + 8722643 = 8723086

Showing the first eight; more decompositions exist.
