Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556832, here are decompositions:

5 + 31556827 = 31556832
19 + 31556813 = 31556832
29 + 31556803 = 31556832
53 + 31556779 = 31556832
61 + 31556771 = 31556832
179 + 31556653 = 31556832
193 + 31556639 = 31556832
331 + 31556501 = 31556832

Showing the first eight; more decompositions exist.
