Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472356, here are decompositions:

5 + 31472351 = 31472356
17 + 31472339 = 31472356
173 + 31472183 = 31472356
197 + 31472159 = 31472356
233 + 31472123 = 31472356
353 + 31472003 = 31472356
389 + 31471967 = 31472356
449 + 31471907 = 31472356

Showing the first eight; more decompositions exist.
