Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590460, here are decompositions:

17 + 31590443 = 31590460
47 + 31590413 = 31590460
59 + 31590401 = 31590460
89 + 31590371 = 31590460
107 + 31590353 = 31590460
191 + 31590269 = 31590460
197 + 31590263 = 31590460
311 + 31590149 = 31590460

Showing the first eight; more decompositions exist.
