Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556294, here are decompositions:

151 + 31556143 = 31556294
181 + 31556113 = 31556294
283 + 31556011 = 31556294
313 + 31555981 = 31556294
337 + 31555957 = 31556294
373 + 31555921 = 31556294
421 + 31555873 = 31556294
577 + 31555717 = 31556294

Showing the first eight; more decompositions exist.
