Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556354, here are decompositions:

13 + 31556341 = 31556354
31 + 31556323 = 31556354
61 + 31556293 = 31556354
211 + 31556143 = 31556354
241 + 31556113 = 31556354
373 + 31555981 = 31556354
397 + 31555957 = 31556354
421 + 31555933 = 31556354

Showing the first eight; more decompositions exist.
