Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615336, here are decompositions:

3 + 31615333 = 31615336
23 + 31615313 = 31615336
107 + 31615229 = 31615336
149 + 31615187 = 31615336
167 + 31615169 = 31615336
173 + 31615163 = 31615336
227 + 31615109 = 31615336
239 + 31615097 = 31615336

Showing the first eight; more decompositions exist.
