Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567262, here are decompositions:

31 + 31567231 = 31567262
43 + 31567219 = 31567262
109 + 31567153 = 31567262
283 + 31566979 = 31567262
499 + 31566763 = 31567262
631 + 31566631 = 31567262
673 + 31566589 = 31567262
739 + 31566523 = 31567262

Showing the first eight; more decompositions exist.
