Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568094, here are decompositions:

7 + 31568087 = 31568094
11 + 31568083 = 31568094
23 + 31568071 = 31568094
53 + 31568041 = 31568094
67 + 31568027 = 31568094
73 + 31568021 = 31568094
113 + 31567981 = 31568094
163 + 31567931 = 31568094

Showing the first eight; more decompositions exist.
