Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597958, here are decompositions:

31 + 31597927 = 31597958
79 + 31597879 = 31597958
157 + 31597801 = 31597958
181 + 31597777 = 31597958
229 + 31597729 = 31597958
241 + 31597717 = 31597958
307 + 31597651 = 31597958
409 + 31597549 = 31597958

Showing the first eight; more decompositions exist.
