Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595460, here are decompositions:

53 + 31595407 = 31595460
67 + 31595393 = 31595460
73 + 31595387 = 31595460
89 + 31595371 = 31595460
97 + 31595363 = 31595460
181 + 31595279 = 31595460
223 + 31595237 = 31595460
241 + 31595219 = 31595460

Showing the first eight; more decompositions exist.
