Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586046, here are decompositions:

43 + 31586003 = 31586046
67 + 31585979 = 31586046
73 + 31585973 = 31586046
83 + 31585963 = 31586046
109 + 31585937 = 31586046
157 + 31585889 = 31586046
197 + 31585849 = 31586046
223 + 31585823 = 31586046

Showing the first eight; more decompositions exist.
