Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516362, here are decompositions:

5 + 31516357 = 31516362
29 + 31516333 = 31516362
43 + 31516319 = 31516362
109 + 31516253 = 31516362
173 + 31516189 = 31516362
179 + 31516183 = 31516362
223 + 31516139 = 31516362
233 + 31516129 = 31516362

Showing the first eight; more decompositions exist.
