Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466382, here are decompositions:

41 + 31466341 = 31466382
53 + 31466329 = 31466382
131 + 31466251 = 31466382
149 + 31466233 = 31466382
239 + 31466143 = 31466382
263 + 31466119 = 31466382
281 + 31466101 = 31466382
293 + 31466089 = 31466382

Showing the first eight; more decompositions exist.
