Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595530, here are decompositions:

47 + 31595483 = 31595530
137 + 31595393 = 31595530
167 + 31595363 = 31595530
251 + 31595279 = 31595530
257 + 31595273 = 31595530
293 + 31595237 = 31595530
311 + 31595219 = 31595530
353 + 31595177 = 31595530

Showing the first eight; more decompositions exist.
