Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519246, here are decompositions:

47 + 31519199 = 31519246
53 + 31519193 = 31519246
137 + 31519109 = 31519246
173 + 31519073 = 31519246
179 + 31519067 = 31519246
197 + 31519049 = 31519246
257 + 31518989 = 31519246
293 + 31518953 = 31519246

Showing the first eight; more decompositions exist.
