Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556474, here are decompositions:

7 + 31556467 = 31556474
13 + 31556461 = 31556474
67 + 31556407 = 31556474
151 + 31556323 = 31556474
181 + 31556293 = 31556474
331 + 31556143 = 31556474
463 + 31556011 = 31556474
541 + 31555933 = 31556474

Showing the first eight; more decompositions exist.
