Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466738, here are decompositions:

7 + 31466731 = 31466738
19 + 31466719 = 31466738
31 + 31466707 = 31466738
67 + 31466671 = 31466738
109 + 31466629 = 31466738
151 + 31466587 = 31466738
337 + 31466401 = 31466738
349 + 31466389 = 31466738

Showing the first eight; more decompositions exist.
