Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586322, here are decompositions:

11 + 31586311 = 31586322
41 + 31586281 = 31586322
151 + 31586171 = 31586322
181 + 31586141 = 31586322
191 + 31586131 = 31586322
263 + 31586059 = 31586322
269 + 31586053 = 31586322
349 + 31585973 = 31586322

Showing the first eight; more decompositions exist.
