Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466330, here are decompositions:

3 + 31466327 = 31466330
43 + 31466287 = 31466330
67 + 31466263 = 31466330
73 + 31466257 = 31466330
79 + 31466251 = 31466330
97 + 31466233 = 31466330
109 + 31466221 = 31466330
157 + 31466173 = 31466330

Showing the first eight; more decompositions exist.
