Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589766, here are decompositions:

7 + 31589759 = 31589766
29 + 31589737 = 31589766
59 + 31589707 = 31589766
73 + 31589693 = 31589766
83 + 31589683 = 31589766
107 + 31589659 = 31589766
199 + 31589567 = 31589766
227 + 31589539 = 31589766

Showing the first eight; more decompositions exist.
