Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514974, here are decompositions:

5 + 31514969 = 31514974
11 + 31514963 = 31514974
41 + 31514933 = 31514974
137 + 31514837 = 31514974
191 + 31514783 = 31514974
233 + 31514741 = 31514974
311 + 31514663 = 31514974
347 + 31514627 = 31514974

Showing the first eight; more decompositions exist.
