Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484322, here are decompositions:

5 + 31484317 = 31484322
19 + 31484303 = 31484322
41 + 31484281 = 31484322
83 + 31484239 = 31484322
113 + 31484209 = 31484322
179 + 31484143 = 31484322
193 + 31484129 = 31484322
229 + 31484093 = 31484322

Showing the first eight; more decompositions exist.
