Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536956, here are decompositions:

13 + 31536943 = 31536956
19 + 31536937 = 31536956
109 + 31536847 = 31536956
127 + 31536829 = 31536956
163 + 31536793 = 31536956
223 + 31536733 = 31536956
349 + 31536607 = 31536956
457 + 31536499 = 31536956

Showing the first eight; more decompositions exist.
