Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595470, here are decompositions:

3 + 31595467 = 31595470
83 + 31595387 = 31595470
107 + 31595363 = 31595470
191 + 31595279 = 31595470
197 + 31595273 = 31595470
227 + 31595243 = 31595470
233 + 31595237 = 31595470
251 + 31595219 = 31595470

Showing the first eight; more decompositions exist.
