Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595302, here are decompositions:

23 + 31595279 = 31595302
29 + 31595273 = 31595302
59 + 31595243 = 31595302
83 + 31595219 = 31595302
113 + 31595189 = 31595302
239 + 31595063 = 31595302
281 + 31595021 = 31595302
293 + 31595009 = 31595302

Showing the first eight; more decompositions exist.
