Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466870, here are decompositions:

3 + 31466867 = 31466870
13 + 31466857 = 31466870
79 + 31466791 = 31466870
139 + 31466731 = 31466870
151 + 31466719 = 31466870
157 + 31466713 = 31466870
163 + 31466707 = 31466870
181 + 31466689 = 31466870

Showing the first eight; more decompositions exist.
