Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556246, here are decompositions:

3 + 31556243 = 31556246
97 + 31556149 = 31556246
103 + 31556143 = 31556246
277 + 31555969 = 31556246
307 + 31555939 = 31556246
313 + 31555933 = 31556246
373 + 31555873 = 31556246
433 + 31555813 = 31556246

Showing the first eight; more decompositions exist.
