Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590382, here are decompositions:

11 + 31590371 = 31590382
29 + 31590353 = 31590382
113 + 31590269 = 31590382
233 + 31590149 = 31590382
293 + 31590089 = 31590382
311 + 31590071 = 31590382
401 + 31589981 = 31590382
491 + 31589891 = 31590382

Showing the first eight; more decompositions exist.
