Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465322, here are decompositions:

13 + 31465309 = 31465322
79 + 31465243 = 31465322
139 + 31465183 = 31465322
193 + 31465129 = 31465322
199 + 31465123 = 31465322
211 + 31465111 = 31465322
223 + 31465099 = 31465322
283 + 31465039 = 31465322

Showing the first eight; more decompositions exist.
