Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466874, here are decompositions:

7 + 31466867 = 31466874
17 + 31466857 = 31466874
53 + 31466821 = 31466874
83 + 31466791 = 31466874
167 + 31466707 = 31466874
181 + 31466693 = 31466874
277 + 31466597 = 31466874
311 + 31466563 = 31466874

Showing the first eight; more decompositions exist.
