Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514814, here are decompositions:

31 + 31514783 = 31514814
43 + 31514771 = 31514814
73 + 31514741 = 31514814
83 + 31514731 = 31514814
127 + 31514687 = 31514814
151 + 31514663 = 31514814
173 + 31514641 = 31514814
241 + 31514573 = 31514814

Showing the first eight; more decompositions exist.
