Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590586, here are decompositions:

3 + 31590583 = 31590586
29 + 31590557 = 31590586
107 + 31590479 = 31590586
173 + 31590413 = 31590586
233 + 31590353 = 31590586
317 + 31590269 = 31590586
449 + 31590137 = 31590586
719 + 31589867 = 31590586

Showing the first eight; more decompositions exist.
