Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514956, here are decompositions:

23 + 31514933 = 31514956
107 + 31514849 = 31514956
167 + 31514789 = 31514956
173 + 31514783 = 31514956
269 + 31514687 = 31514956
293 + 31514663 = 31514956
383 + 31514573 = 31514956
419 + 31514537 = 31514956

Showing the first eight; more decompositions exist.
