Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514106, here are decompositions:

5 + 31514101 = 31514106
47 + 31514059 = 31514106
83 + 31514023 = 31514106
139 + 31513967 = 31514106
149 + 31513957 = 31514106
163 + 31513943 = 31514106
179 + 31513927 = 31514106
227 + 31513879 = 31514106

Showing the first eight; more decompositions exist.
