Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514856, here are decompositions:

7 + 31514849 = 31514856
17 + 31514839 = 31514856
19 + 31514837 = 31514856
67 + 31514789 = 31514856
73 + 31514783 = 31514856
167 + 31514689 = 31514856
193 + 31514663 = 31514856
227 + 31514629 = 31514856

Showing the first eight; more decompositions exist.
