Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567126, here are decompositions:

83 + 31567043 = 31567126
263 + 31566863 = 31567126
389 + 31566737 = 31567126
467 + 31566659 = 31567126
599 + 31566527 = 31567126
653 + 31566473 = 31567126
677 + 31566449 = 31567126
683 + 31566443 = 31567126

Showing the first eight; more decompositions exist.
