Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460086, here are decompositions:

23 + 31460063 = 31460086
137 + 31459949 = 31460086
149 + 31459937 = 31460086
227 + 31459859 = 31460086
233 + 31459853 = 31460086
239 + 31459847 = 31460086
257 + 31459829 = 31460086
353 + 31459733 = 31460086

Showing the first eight; more decompositions exist.
