Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457914, here are decompositions:

3 + 31457911 = 31457914
11 + 31457903 = 31457914
53 + 31457861 = 31457914
71 + 31457843 = 31457914
83 + 31457831 = 31457914
197 + 31457717 = 31457914
227 + 31457687 = 31457914
233 + 31457681 = 31457914

Showing the first eight; more decompositions exist.
