Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560892, here are decompositions:

5 + 31560887 = 31560892
23 + 31560869 = 31560892
29 + 31560863 = 31560892
101 + 31560791 = 31560892
173 + 31560719 = 31560892
179 + 31560713 = 31560892
263 + 31560629 = 31560892
359 + 31560533 = 31560892

Showing the first eight; more decompositions exist.
