Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475056, here are decompositions:

3 + 31475053 = 31475056
47 + 31475009 = 31475056
59 + 31474997 = 31475056
227 + 31474829 = 31475056
293 + 31474763 = 31475056
383 + 31474673 = 31475056
479 + 31474577 = 31475056
653 + 31474403 = 31475056

Showing the first eight; more decompositions exist.
