Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466938, here are decompositions:

5 + 31466933 = 31466938
71 + 31466867 = 31466938
89 + 31466849 = 31466938
179 + 31466759 = 31466938
281 + 31466657 = 31466938
311 + 31466627 = 31466938
389 + 31466549 = 31466938
557 + 31466381 = 31466938

Showing the first eight; more decompositions exist.
