Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556694, here are decompositions:

7 + 31556687 = 31556694
41 + 31556653 = 31556694
47 + 31556647 = 31556694
137 + 31556557 = 31556694
157 + 31556537 = 31556694
193 + 31556501 = 31556694
227 + 31556467 = 31556694
233 + 31556461 = 31556694

Showing the first eight; more decompositions exist.
