Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624322, here are decompositions:

181 + 31624141 = 31624322
193 + 31624129 = 31624322
421 + 31623901 = 31624322
601 + 31623721 = 31624322
619 + 31623703 = 31624322
733 + 31623589 = 31624322
811 + 31623511 = 31624322
823 + 31623499 = 31624322

Showing the first eight; more decompositions exist.
