Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475914, here are decompositions:

3 + 31475911 = 31475914
5 + 31475909 = 31475914
101 + 31475813 = 31475914
137 + 31475777 = 31475914
233 + 31475681 = 31475914
317 + 31475597 = 31475914
443 + 31475471 = 31475914
461 + 31475453 = 31475914

Showing the first eight; more decompositions exist.
