Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516166, here are decompositions:

7 + 31516159 = 31516166
13 + 31516153 = 31516166
37 + 31516129 = 31516166
43 + 31516123 = 31516166
67 + 31516099 = 31516166
79 + 31516087 = 31516166
139 + 31516027 = 31516166
229 + 31515937 = 31516166

Showing the first eight; more decompositions exist.
