Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514884, here are decompositions:

47 + 31514837 = 31514884
101 + 31514783 = 31514884
113 + 31514771 = 31514884
197 + 31514687 = 31514884
257 + 31514627 = 31514884
311 + 31514573 = 31514884
347 + 31514537 = 31514884
461 + 31514423 = 31514884

Showing the first eight; more decompositions exist.
