Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466318, here are decompositions:

31 + 31466287 = 31466318
61 + 31466257 = 31466318
67 + 31466251 = 31466318
97 + 31466221 = 31466318
181 + 31466137 = 31466318
199 + 31466119 = 31466318
211 + 31466107 = 31466318
229 + 31466089 = 31466318

Showing the first eight; more decompositions exist.
