Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514968, here are decompositions:

5 + 31514963 = 31514968
131 + 31514837 = 31514968
179 + 31514789 = 31514968
197 + 31514771 = 31514968
227 + 31514741 = 31514968
281 + 31514687 = 31514968
389 + 31514579 = 31514968
431 + 31514537 = 31514968

Showing the first eight; more decompositions exist.
