Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516182, here are decompositions:

23 + 31516159 = 31516182
29 + 31516153 = 31516182
43 + 31516139 = 31516182
53 + 31516129 = 31516182
59 + 31516123 = 31516182
73 + 31516109 = 31516182
79 + 31516103 = 31516182
83 + 31516099 = 31516182

Showing the first eight; more decompositions exist.
