Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516176, here are decompositions:

17 + 31516159 = 31516176
19 + 31516157 = 31516176
23 + 31516153 = 31516176
37 + 31516139 = 31516176
47 + 31516129 = 31516176
53 + 31516123 = 31516176
67 + 31516109 = 31516176
73 + 31516103 = 31516176

Showing the first eight; more decompositions exist.
