Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556366, here are decompositions:

13 + 31556353 = 31556366
43 + 31556323 = 31556366
73 + 31556293 = 31556366
223 + 31556143 = 31556366
367 + 31555999 = 31556366
397 + 31555969 = 31556366
409 + 31555957 = 31556366
433 + 31555933 = 31556366

Showing the first eight; more decompositions exist.
