Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500952, here are decompositions:

5 + 31500947 = 31500952
11 + 31500941 = 31500952
29 + 31500923 = 31500952
53 + 31500899 = 31500952
89 + 31500863 = 31500952
179 + 31500773 = 31500952
233 + 31500719 = 31500952
239 + 31500713 = 31500952

Showing the first eight; more decompositions exist.
