Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514944, here are decompositions:

11 + 31514933 = 31514944
107 + 31514837 = 31514944
173 + 31514771 = 31514944
257 + 31514687 = 31514944
281 + 31514663 = 31514944
317 + 31514627 = 31514944
431 + 31514513 = 31514944
467 + 31514477 = 31514944

Showing the first eight; more decompositions exist.
