Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475922, here are decompositions:

11 + 31475911 = 31475922
13 + 31475909 = 31475922
73 + 31475849 = 31475922
109 + 31475813 = 31475922
151 + 31475771 = 31475922
173 + 31475749 = 31475922
239 + 31475683 = 31475922
241 + 31475681 = 31475922

Showing the first eight; more decompositions exist.
