Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585034, here are decompositions:

67 + 31584967 = 31585034
73 + 31584961 = 31585034
127 + 31584907 = 31585034
181 + 31584853 = 31585034
211 + 31584823 = 31585034
277 + 31584757 = 31585034
331 + 31584703 = 31585034
337 + 31584697 = 31585034

Showing the first eight; more decompositions exist.
