Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568096, here are decompositions:

13 + 31568083 = 31568096
37 + 31568059 = 31568096
97 + 31567999 = 31568096
277 + 31567819 = 31568096
283 + 31567813 = 31568096
367 + 31567729 = 31568096
379 + 31567717 = 31568096
397 + 31567699 = 31568096

Showing the first eight; more decompositions exist.
