Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590322, here are decompositions:

53 + 31590269 = 31590322
59 + 31590263 = 31590322
173 + 31590149 = 31590322
233 + 31590089 = 31590322
251 + 31590071 = 31590322
311 + 31590011 = 31590322
431 + 31589891 = 31590322
461 + 31589861 = 31590322

Showing the first eight; more decompositions exist.
