Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556962, here are decompositions:

5 + 31556957 = 31556962
23 + 31556939 = 31556962
53 + 31556909 = 31556962
149 + 31556813 = 31556962
191 + 31556771 = 31556962
461 + 31556501 = 31556962
653 + 31556309 = 31556962
659 + 31556303 = 31556962

Showing the first eight; more decompositions exist.
