Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453322, here are decompositions:

73 + 31453249 = 31453322
151 + 31453171 = 31453322
163 + 31453159 = 31453322
181 + 31453141 = 31453322
283 + 31453039 = 31453322
349 + 31452973 = 31453322
379 + 31452943 = 31453322
421 + 31452901 = 31453322

Showing the first eight; more decompositions exist.
