Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472326, here are decompositions:

167 + 31472159 = 31472326
173 + 31472153 = 31472326
257 + 31472069 = 31472326
359 + 31471967 = 31472326
419 + 31471907 = 31472326
443 + 31471883 = 31472326
503 + 31471823 = 31472326
563 + 31471763 = 31472326

Showing the first eight; more decompositions exist.
