Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556322, here are decompositions:

13 + 31556309 = 31556322
19 + 31556303 = 31556322
29 + 31556293 = 31556322
43 + 31556279 = 31556322
73 + 31556249 = 31556322
79 + 31556243 = 31556322
173 + 31556149 = 31556322
179 + 31556143 = 31556322

Showing the first eight; more decompositions exist.
