Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597822, here are decompositions:

29 + 31597793 = 31597822
59 + 31597763 = 31597822
83 + 31597739 = 31597822
101 + 31597721 = 31597822
149 + 31597673 = 31597822
251 + 31597571 = 31597822
281 + 31597541 = 31597822
569 + 31597253 = 31597822

Showing the first eight; more decompositions exist.
