Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466366, here are decompositions:

37 + 31466329 = 31466366
79 + 31466287 = 31466366
103 + 31466263 = 31466366
109 + 31466257 = 31466366
193 + 31466173 = 31466366
223 + 31466143 = 31466366
229 + 31466137 = 31466366
277 + 31466089 = 31466366

Showing the first eight; more decompositions exist.
