Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556982, here are decompositions:

43 + 31556939 = 31556982
59 + 31556923 = 31556982
71 + 31556911 = 31556982
73 + 31556909 = 31556982
113 + 31556869 = 31556982
179 + 31556803 = 31556982
211 + 31556771 = 31556982
241 + 31556741 = 31556982

Showing the first eight; more decompositions exist.
