Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560956, here are decompositions:

13 + 31560943 = 31560956
109 + 31560847 = 31560956
157 + 31560799 = 31560956
199 + 31560757 = 31560956
277 + 31560679 = 31560956
283 + 31560673 = 31560956
367 + 31560589 = 31560956
373 + 31560583 = 31560956

Showing the first eight; more decompositions exist.
