Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460170, here are decompositions:

3 + 31460167 = 31460170
41 + 31460129 = 31460170
107 + 31460063 = 31460170
233 + 31459937 = 31460170
239 + 31459931 = 31460170
311 + 31459859 = 31460170
317 + 31459853 = 31460170
461 + 31459709 = 31460170

Showing the first eight; more decompositions exist.
