Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536968, here are decompositions:

31 + 31536937 = 31536968
97 + 31536871 = 31536968
139 + 31536829 = 31536968
271 + 31536697 = 31536968
439 + 31536529 = 31536968
487 + 31536481 = 31536968
571 + 31536397 = 31536968
577 + 31536391 = 31536968

Showing the first eight; more decompositions exist.
