Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596346, here are decompositions:

29 + 31596317 = 31596346
53 + 31596293 = 31596346
137 + 31596209 = 31596346
227 + 31596119 = 31596346
317 + 31596029 = 31596346
479 + 31595867 = 31596346
563 + 31595783 = 31596346
569 + 31595777 = 31596346

Showing the first eight; more decompositions exist.
