Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586132, here are decompositions:

31 + 31586101 = 31586132
73 + 31586059 = 31586132
79 + 31586053 = 31586132
229 + 31585903 = 31586132
283 + 31585849 = 31586132
349 + 31585783 = 31586132
631 + 31585501 = 31586132
673 + 31585459 = 31586132

Showing the first eight; more decompositions exist.
