Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466398, here are decompositions:

11 + 31466387 = 31466398
17 + 31466381 = 31466398
71 + 31466327 = 31466398
107 + 31466291 = 31466398
149 + 31466249 = 31466398
191 + 31466207 = 31466398
347 + 31466051 = 31466398
419 + 31465979 = 31466398

Showing the first eight; more decompositions exist.
