Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471914, here are decompositions:

7 + 31471907 = 31471914
13 + 31471901 = 31471914
31 + 31471883 = 31471914
83 + 31471831 = 31471914
127 + 31471787 = 31471914
151 + 31471763 = 31471914
211 + 31471703 = 31471914
233 + 31471681 = 31471914

Showing the first eight; more decompositions exist.
