Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514994, here are decompositions:

13 + 31514981 = 31514994
31 + 31514963 = 31514994
47 + 31514947 = 31514994
61 + 31514933 = 31514994
83 + 31514911 = 31514994
101 + 31514893 = 31514994
157 + 31514837 = 31514994
211 + 31514783 = 31514994

Showing the first eight; more decompositions exist.
