Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466346, here are decompositions:

5 + 31466341 = 31466346
17 + 31466329 = 31466346
19 + 31466327 = 31466346
59 + 31466287 = 31466346
83 + 31466263 = 31466346
89 + 31466257 = 31466346
97 + 31466249 = 31466346
113 + 31466233 = 31466346

Showing the first eight; more decompositions exist.
