Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466584, here are decompositions:

197 + 31466387 = 31466584
257 + 31466327 = 31466584
293 + 31466291 = 31466584
521 + 31466063 = 31466584
827 + 31465757 = 31466584
857 + 31465727 = 31466584
887 + 31465697 = 31466584
911 + 31465673 = 31466584

Showing the first eight; more decompositions exist.
