Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597834, here are decompositions:

11 + 31597823 = 31597834
41 + 31597793 = 31597834
71 + 31597763 = 31597834
113 + 31597721 = 31597834
137 + 31597697 = 31597834
263 + 31597571 = 31597834
293 + 31597541 = 31597834
467 + 31597367 = 31597834

Showing the first eight; more decompositions exist.
