Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466822, here are decompositions:

31 + 31466791 = 31466822
73 + 31466749 = 31466822
103 + 31466719 = 31466822
109 + 31466713 = 31466822
151 + 31466671 = 31466822
193 + 31466629 = 31466822
421 + 31466401 = 31466822
433 + 31466389 = 31466822

Showing the first eight; more decompositions exist.
