Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615204, here are decompositions:

11 + 31615193 = 31615204
17 + 31615187 = 31615204
41 + 31615163 = 31615204
107 + 31615097 = 31615204
191 + 31615013 = 31615204
197 + 31615007 = 31615204
251 + 31614953 = 31615204
263 + 31614941 = 31615204

Showing the first eight; more decompositions exist.
