Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595514, here are decompositions:

31 + 31595483 = 31595514
47 + 31595467 = 31595514
107 + 31595407 = 31595514
127 + 31595387 = 31595514
131 + 31595383 = 31595514
151 + 31595363 = 31595514
241 + 31595273 = 31595514
263 + 31595251 = 31595514

Showing the first eight; more decompositions exist.
