Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583322, here are decompositions:

41 + 31583281 = 31583322
53 + 31583269 = 31583322
151 + 31583171 = 31583322
163 + 31583159 = 31583322
191 + 31583131 = 31583322
241 + 31583081 = 31583322
271 + 31583051 = 31583322
373 + 31582949 = 31583322

Showing the first eight; more decompositions exist.
