Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466950, here are decompositions:

17 + 31466933 = 31466950
83 + 31466867 = 31466950
101 + 31466849 = 31466950
191 + 31466759 = 31466950
197 + 31466753 = 31466950
257 + 31466693 = 31466950
293 + 31466657 = 31466950
353 + 31466597 = 31466950

Showing the first eight; more decompositions exist.
