Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461514, here are decompositions:

101 + 31461413 = 31461514
173 + 31461341 = 31461514
233 + 31461281 = 31461514
353 + 31461161 = 31461514
401 + 31461113 = 31461514
467 + 31461047 = 31461514
503 + 31461011 = 31461514
563 + 31460951 = 31461514

Showing the first eight; more decompositions exist.
