Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590052, here are decompositions:

41 + 31590011 = 31590052
71 + 31589981 = 31590052
191 + 31589861 = 31590052
233 + 31589819 = 31590052
281 + 31589771 = 31590052
293 + 31589759 = 31590052
359 + 31589693 = 31590052
419 + 31589633 = 31590052

Showing the first eight; more decompositions exist.
