Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556204, here are decompositions:

3 + 31556201 = 31556204
61 + 31556143 = 31556204
193 + 31556011 = 31556204
223 + 31555981 = 31556204
271 + 31555933 = 31556204
283 + 31555921 = 31556204
313 + 31555891 = 31556204
331 + 31555873 = 31556204

Showing the first eight; more decompositions exist.
