Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556336, here are decompositions:

13 + 31556323 = 31556336
43 + 31556293 = 31556336
193 + 31556143 = 31556336
223 + 31556113 = 31556336
337 + 31555999 = 31556336
367 + 31555969 = 31556336
379 + 31555957 = 31556336
397 + 31555939 = 31556336

Showing the first eight; more decompositions exist.
