Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556346, here are decompositions:

5 + 31556341 = 31556346
23 + 31556323 = 31556346
37 + 31556309 = 31556346
43 + 31556303 = 31556346
53 + 31556293 = 31556346
67 + 31556279 = 31556346
97 + 31556249 = 31556346
103 + 31556243 = 31556346

Showing the first eight; more decompositions exist.
