Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590892, here are decompositions:

5 + 31590887 = 31590892
59 + 31590833 = 31590892
89 + 31590803 = 31590892
101 + 31590791 = 31590892
233 + 31590659 = 31590892
449 + 31590443 = 31590892
479 + 31590413 = 31590892
491 + 31590401 = 31590892

Showing the first eight; more decompositions exist.
