Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475956, here are decompositions:

3 + 31475953 = 31475956
47 + 31475909 = 31475956
107 + 31475849 = 31475956
179 + 31475777 = 31475956
359 + 31475597 = 31475956
467 + 31475489 = 31475956
503 + 31475453 = 31475956
563 + 31475393 = 31475956

Showing the first eight; more decompositions exist.
