Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536974, here are decompositions:

31 + 31536943 = 31536974
37 + 31536937 = 31536974
103 + 31536871 = 31536974
127 + 31536847 = 31536974
151 + 31536823 = 31536974
181 + 31536793 = 31536974
241 + 31536733 = 31536974
277 + 31536697 = 31536974

Showing the first eight; more decompositions exist.
