Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555322, here are decompositions:

3 + 31555319 = 31555322
79 + 31555243 = 31555322
151 + 31555171 = 31555322
181 + 31555141 = 31555322
223 + 31555099 = 31555322
229 + 31555093 = 31555322
241 + 31555081 = 31555322
373 + 31554949 = 31555322

Showing the first eight; more decompositions exist.
