Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536944, here are decompositions:

7 + 31536937 = 31536944
73 + 31536871 = 31536944
97 + 31536847 = 31536944
151 + 31536793 = 31536944
211 + 31536733 = 31536944
331 + 31536613 = 31536944
337 + 31536607 = 31536944
463 + 31536481 = 31536944

Showing the first eight; more decompositions exist.
