Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472164, here are decompositions:

5 + 31472159 = 31472164
11 + 31472153 = 31472164
41 + 31472123 = 31472164
173 + 31471991 = 31472164
197 + 31471967 = 31472164
257 + 31471907 = 31472164
263 + 31471901 = 31472164
281 + 31471883 = 31472164

Showing the first eight; more decompositions exist.
