Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536950, here are decompositions:

7 + 31536943 = 31536950
13 + 31536937 = 31536950
79 + 31536871 = 31536950
103 + 31536847 = 31536950
127 + 31536823 = 31536950
157 + 31536793 = 31536950
337 + 31536613 = 31536950
421 + 31536529 = 31536950

Showing the first eight; more decompositions exist.
