Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615456, here are decompositions:

17 + 31615439 = 31615456
53 + 31615403 = 31615456
113 + 31615343 = 31615456
227 + 31615229 = 31615456
239 + 31615217 = 31615456
263 + 31615193 = 31615456
269 + 31615187 = 31615456
293 + 31615163 = 31615456

Showing the first eight; more decompositions exist.
