Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461352, here are decompositions:

3 + 31461349 = 31461352
11 + 31461341 = 31461352
59 + 31461293 = 31461352
71 + 31461281 = 31461352
173 + 31461179 = 31461352
179 + 31461173 = 31461352
191 + 31461161 = 31461352
239 + 31461113 = 31461352

Showing the first eight; more decompositions exist.
