Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595484, here are decompositions:

17 + 31595467 = 31595484
97 + 31595387 = 31595484
101 + 31595383 = 31595484
113 + 31595371 = 31595484
211 + 31595273 = 31595484
233 + 31595251 = 31595484
241 + 31595243 = 31595484
307 + 31595177 = 31595484

Showing the first eight; more decompositions exist.
