Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617412, here are decompositions:

3 + 31617409 = 31617412
5 + 31617407 = 31617412
41 + 31617371 = 31617412
83 + 31617329 = 31617412
131 + 31617281 = 31617412
173 + 31617239 = 31617412
263 + 31617149 = 31617412
311 + 31617101 = 31617412

Showing the first eight; more decompositions exist.
