Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564322, here are decompositions:

61 + 31564261 = 31564322
73 + 31564249 = 31564322
79 + 31564243 = 31564322
151 + 31564171 = 31564322
193 + 31564129 = 31564322
271 + 31564051 = 31564322
313 + 31564009 = 31564322
373 + 31563949 = 31564322

Showing the first eight; more decompositions exist.
