Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560952, here are decompositions:

11 + 31560941 = 31560952
41 + 31560911 = 31560952
83 + 31560869 = 31560952
89 + 31560863 = 31560952
233 + 31560719 = 31560952
239 + 31560713 = 31560952
263 + 31560689 = 31560952
383 + 31560569 = 31560952

Showing the first eight; more decompositions exist.
