Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595598, here are decompositions:

5 + 31595593 = 31595598
17 + 31595581 = 31595598
29 + 31595569 = 31595598
31 + 31595567 = 31595598
131 + 31595467 = 31595598
191 + 31595407 = 31595598
211 + 31595387 = 31595598
227 + 31595371 = 31595598

Showing the first eight; more decompositions exist.
