Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560652, here are decompositions:

5 + 31560647 = 31560652
23 + 31560629 = 31560652
83 + 31560569 = 31560652
251 + 31560401 = 31560652
269 + 31560383 = 31560652
311 + 31560341 = 31560652
353 + 31560299 = 31560652
359 + 31560293 = 31560652

Showing the first eight; more decompositions exist.
