Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590526, here are decompositions:

47 + 31590479 = 31590526
59 + 31590467 = 31590526
83 + 31590443 = 31590526
113 + 31590413 = 31590526
173 + 31590353 = 31590526
257 + 31590269 = 31590526
263 + 31590263 = 31590526
389 + 31590137 = 31590526

Showing the first eight; more decompositions exist.
