Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472056, here are decompositions:

3 + 31472053 = 31472056
53 + 31472003 = 31472056
89 + 31471967 = 31472056
149 + 31471907 = 31472056
173 + 31471883 = 31472056
233 + 31471823 = 31472056
257 + 31471799 = 31472056
269 + 31471787 = 31472056

Showing the first eight; more decompositions exist.
