Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466828, here are decompositions:

7 + 31466821 = 31466828
37 + 31466791 = 31466828
79 + 31466749 = 31466828
97 + 31466731 = 31466828
109 + 31466719 = 31466828
139 + 31466689 = 31466828
157 + 31466671 = 31466828
199 + 31466629 = 31466828

Showing the first eight; more decompositions exist.
