Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516336, here are decompositions:

3 + 31516333 = 31516336
17 + 31516319 = 31516336
83 + 31516253 = 31516336
179 + 31516157 = 31516336
197 + 31516139 = 31516336
227 + 31516109 = 31516336
233 + 31516103 = 31516336
347 + 31515989 = 31516336

Showing the first eight; more decompositions exist.
