Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615414, here are decompositions:

11 + 31615403 = 31615414
23 + 31615391 = 31615414
71 + 31615343 = 31615414
101 + 31615313 = 31615414
197 + 31615217 = 31615414
227 + 31615187 = 31615414
251 + 31615163 = 31615414
317 + 31615097 = 31615414

Showing the first eight; more decompositions exist.
