Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586034, here are decompositions:

31 + 31586003 = 31586034
37 + 31585997 = 31586034
61 + 31585973 = 31586034
71 + 31585963 = 31586034
97 + 31585937 = 31586034
131 + 31585903 = 31586034
197 + 31585837 = 31586034
211 + 31585823 = 31586034

Showing the first eight; more decompositions exist.
