Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615294, here are decompositions:

83 + 31615211 = 31615294
101 + 31615193 = 31615294
107 + 31615187 = 31615294
131 + 31615163 = 31615294
167 + 31615127 = 31615294
197 + 31615097 = 31615294
233 + 31615061 = 31615294
281 + 31615013 = 31615294

Showing the first eight; more decompositions exist.
