Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496952, here are decompositions:

5 + 31496947 = 31496952
31 + 31496921 = 31496952
79 + 31496873 = 31496952
89 + 31496863 = 31496952
173 + 31496779 = 31496952
211 + 31496741 = 31496952
233 + 31496719 = 31496952
281 + 31496671 = 31496952

Showing the first eight; more decompositions exist.
