Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499836, here are decompositions:

3 + 31499833 = 31499836
449 + 31499387 = 31499836
509 + 31499327 = 31499836
569 + 31499267 = 31499836
647 + 31499189 = 31499836
653 + 31499183 = 31499836
677 + 31499159 = 31499836
773 + 31499063 = 31499836

Showing the first eight; more decompositions exist.
