Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466974, here are decompositions:

5 + 31466969 = 31466974
23 + 31466951 = 31466974
41 + 31466933 = 31466974
101 + 31466873 = 31466974
107 + 31466867 = 31466974
281 + 31466693 = 31466974
317 + 31466657 = 31466974
347 + 31466627 = 31466974

Showing the first eight; more decompositions exist.
