Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490952, here are decompositions:

13 + 31490939 = 31490952
131 + 31490821 = 31490952
173 + 31490779 = 31490952
179 + 31490773 = 31490952
211 + 31490741 = 31490952
223 + 31490729 = 31490952
239 + 31490713 = 31490952
293 + 31490659 = 31490952

Showing the first eight; more decompositions exist.
