Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507014, here are decompositions:

5 + 31507009 = 31507014
37 + 31506977 = 31507014
41 + 31506973 = 31507014
83 + 31506931 = 31507014
103 + 31506911 = 31507014
107 + 31506907 = 31507014
127 + 31506887 = 31507014
173 + 31506841 = 31507014

Showing the first eight; more decompositions exist.
