Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595232, here are decompositions:

13 + 31595219 = 31595232
23 + 31595209 = 31595232
43 + 31595189 = 31595232
59 + 31595173 = 31595232
131 + 31595101 = 31595232
173 + 31595059 = 31595232
211 + 31595021 = 31595232
223 + 31595009 = 31595232

Showing the first eight; more decompositions exist.
