Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597860, here are decompositions:

17 + 31597843 = 31597860
37 + 31597823 = 31597860
59 + 31597801 = 31597860
67 + 31597793 = 31597860
83 + 31597777 = 31597860
97 + 31597763 = 31597860
131 + 31597729 = 31597860
139 + 31597721 = 31597860

Showing the first eight; more decompositions exist.
