Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544322, here are decompositions:

11 + 31544311 = 31544322
41 + 31544281 = 31544322
101 + 31544221 = 31544322
109 + 31544213 = 31544322
151 + 31544171 = 31544322
191 + 31544131 = 31544322
223 + 31544099 = 31544322
233 + 31544089 = 31544322

Showing the first eight; more decompositions exist.
