Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501896, here are decompositions:

17 + 31501879 = 31501896
47 + 31501849 = 31501896
73 + 31501823 = 31501896
89 + 31501807 = 31501896
137 + 31501759 = 31501896
197 + 31501699 = 31501896
227 + 31501669 = 31501896
263 + 31501633 = 31501896

Showing the first eight; more decompositions exist.
