Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590376, here are decompositions:

5 + 31590371 = 31590376
23 + 31590353 = 31590376
107 + 31590269 = 31590376
113 + 31590263 = 31590376
227 + 31590149 = 31590376
239 + 31590137 = 31590376
509 + 31589867 = 31590376
557 + 31589819 = 31590376

Showing the first eight; more decompositions exist.
