Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595332, here are decompositions:

53 + 31595279 = 31595332
59 + 31595273 = 31595332
89 + 31595243 = 31595332
113 + 31595219 = 31595332
191 + 31595141 = 31595332
269 + 31595063 = 31595332
311 + 31595021 = 31595332
401 + 31594931 = 31595332

Showing the first eight; more decompositions exist.
