Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514776, here are decompositions:

5 + 31514771 = 31514776
89 + 31514687 = 31514776
113 + 31514663 = 31514776
149 + 31514627 = 31514776
197 + 31514579 = 31514776
239 + 31514537 = 31514776
263 + 31514513 = 31514776
347 + 31514429 = 31514776

Showing the first eight; more decompositions exist.
