Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567456, here are decompositions:

5 + 31567451 = 31567456
29 + 31567427 = 31567456
59 + 31567397 = 31567456
593 + 31566863 = 31567456
617 + 31566839 = 31567456
653 + 31566803 = 31567456
659 + 31566797 = 31567456
719 + 31566737 = 31567456

Showing the first eight; more decompositions exist.
