Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514822, here are decompositions:

151 + 31514671 = 31514822
181 + 31514641 = 31514822
193 + 31514629 = 31514822
223 + 31514599 = 31514822
271 + 31514551 = 31514822
349 + 31514473 = 31514822
373 + 31514449 = 31514822
421 + 31514401 = 31514822

Showing the first eight; more decompositions exist.
