Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517322, here are decompositions:

79 + 31517243 = 31517322
173 + 31517149 = 31517322
283 + 31517039 = 31517322
311 + 31517011 = 31517322
349 + 31516973 = 31517322
433 + 31516889 = 31517322
443 + 31516879 = 31517322
503 + 31516819 = 31517322

Showing the first eight; more decompositions exist.
