Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586058, here are decompositions:

5 + 31586053 = 31586058
61 + 31585997 = 31586058
79 + 31585979 = 31586058
241 + 31585817 = 31586058
277 + 31585781 = 31586058
281 + 31585777 = 31586058
307 + 31585751 = 31586058
367 + 31585691 = 31586058

Showing the first eight; more decompositions exist.
