Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595958, here are decompositions:

29 + 31595929 = 31595958
89 + 31595869 = 31595958
127 + 31595831 = 31595958
151 + 31595807 = 31595958
181 + 31595777 = 31595958
227 + 31595731 = 31595958
239 + 31595719 = 31595958
241 + 31595717 = 31595958

Showing the first eight; more decompositions exist.
