Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614328, here are decompositions:

101 + 31614227 = 31614328
131 + 31614197 = 31614328
149 + 31614179 = 31614328
167 + 31614161 = 31614328
257 + 31614071 = 31614328
401 + 31613927 = 31614328
461 + 31613867 = 31614328
467 + 31613861 = 31614328

Showing the first eight; more decompositions exist.
