Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556376, here are decompositions:

23 + 31556353 = 31556376
53 + 31556323 = 31556376
67 + 31556309 = 31556376
73 + 31556303 = 31556376
83 + 31556293 = 31556376
97 + 31556279 = 31556376
127 + 31556249 = 31556376
227 + 31556149 = 31556376

Showing the first eight; more decompositions exist.
