Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568124, here are decompositions:

17 + 31568107 = 31568124
37 + 31568087 = 31568124
41 + 31568083 = 31568124
53 + 31568071 = 31568124
83 + 31568041 = 31568124
97 + 31568027 = 31568124
103 + 31568021 = 31568124
163 + 31567961 = 31568124

Showing the first eight; more decompositions exist.
