Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514100, here are decompositions:

19 + 31514081 = 31514100
41 + 31514059 = 31514100
113 + 31513987 = 31514100
157 + 31513943 = 31514100
173 + 31513927 = 31514100
223 + 31513877 = 31514100
227 + 31513873 = 31514100
251 + 31513849 = 31514100

Showing the first eight; more decompositions exist.
