Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518322, here are decompositions:

41 + 31518281 = 31518322
83 + 31518239 = 31518322
113 + 31518209 = 31518322
149 + 31518173 = 31518322
233 + 31518089 = 31518322
359 + 31517963 = 31518322
443 + 31517879 = 31518322
461 + 31517861 = 31518322

Showing the first eight; more decompositions exist.
