Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560794, here are decompositions:

3 + 31560791 = 31560794
37 + 31560757 = 31560794
43 + 31560751 = 31560794
163 + 31560631 = 31560794
211 + 31560583 = 31560794
271 + 31560523 = 31560794
487 + 31560307 = 31560794
547 + 31560247 = 31560794

Showing the first eight; more decompositions exist.
