Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567322, here are decompositions:

43 + 31567279 = 31567322
103 + 31567219 = 31567322
109 + 31567213 = 31567322
349 + 31566973 = 31567322
421 + 31566901 = 31567322
613 + 31566709 = 31567322
691 + 31566631 = 31567322
733 + 31566589 = 31567322

Showing the first eight; more decompositions exist.
