Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466466, here are decompositions:

79 + 31466387 = 31466466
137 + 31466329 = 31466466
139 + 31466327 = 31466466
179 + 31466287 = 31466466
233 + 31466233 = 31466466
293 + 31466173 = 31466466
347 + 31466119 = 31466466
359 + 31466107 = 31466466

Showing the first eight; more decompositions exist.
