Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556360, here are decompositions:

7 + 31556353 = 31556360
19 + 31556341 = 31556360
37 + 31556323 = 31556360
67 + 31556293 = 31556360
211 + 31556149 = 31556360
349 + 31556011 = 31556360
379 + 31555981 = 31556360
421 + 31555939 = 31556360

Showing the first eight; more decompositions exist.
