Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514330, here are decompositions:

109 + 31514221 = 31514330
139 + 31514191 = 31514330
181 + 31514149 = 31514330
229 + 31514101 = 31514330
271 + 31514059 = 31514330
307 + 31514023 = 31514330
373 + 31513957 = 31514330
439 + 31513891 = 31514330

Showing the first eight; more decompositions exist.
