Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514372, here are decompositions:

151 + 31514221 = 31514372
181 + 31514191 = 31514372
223 + 31514149 = 31514372
229 + 31514143 = 31514372
271 + 31514101 = 31514372
313 + 31514059 = 31514372
349 + 31514023 = 31514372
499 + 31513873 = 31514372

Showing the first eight; more decompositions exist.
