Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568088, here are decompositions:

5 + 31568083 = 31568088
17 + 31568071 = 31568088
29 + 31568059 = 31568088
47 + 31568041 = 31568088
61 + 31568027 = 31568088
67 + 31568021 = 31568088
89 + 31567999 = 31568088
107 + 31567981 = 31568088

Showing the first eight; more decompositions exist.
