Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597848, here are decompositions:

5 + 31597843 = 31597848
47 + 31597801 = 31597848
71 + 31597777 = 31597848
109 + 31597739 = 31597848
127 + 31597721 = 31597848
131 + 31597717 = 31597848
151 + 31597697 = 31597848
197 + 31597651 = 31597848

Showing the first eight; more decompositions exist.
