Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614040, here are decompositions:

113 + 31613927 = 31614040
173 + 31613867 = 31614040
179 + 31613861 = 31614040
197 + 31613843 = 31614040
233 + 31613807 = 31614040
239 + 31613801 = 31614040
257 + 31613783 = 31614040
401 + 31613639 = 31614040

Showing the first eight; more decompositions exist.
