Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580952, here are decompositions:

23 + 31580929 = 31580952
41 + 31580911 = 31580952
61 + 31580891 = 31580952
131 + 31580821 = 31580952
163 + 31580789 = 31580952
173 + 31580779 = 31580952
211 + 31580741 = 31580952
233 + 31580719 = 31580952

Showing the first eight; more decompositions exist.
