Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512244, here are decompositions:

53 + 31512191 = 31512244
83 + 31512161 = 31512244
131 + 31512113 = 31512244
173 + 31512071 = 31512244
227 + 31512017 = 31512244
233 + 31512011 = 31512244
251 + 31511993 = 31512244
263 + 31511981 = 31512244

Showing the first eight; more decompositions exist.
