Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556954, here are decompositions:

31 + 31556923 = 31556954
43 + 31556911 = 31556954
97 + 31556857 = 31556954
127 + 31556827 = 31556954
151 + 31556803 = 31556954
307 + 31556647 = 31556954
397 + 31556557 = 31556954
487 + 31556467 = 31556954

Showing the first eight; more decompositions exist.
