Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466598, here are decompositions:

11 + 31466587 = 31466598
197 + 31466401 = 31466598
211 + 31466387 = 31466598
257 + 31466341 = 31466598
269 + 31466329 = 31466598
271 + 31466327 = 31466598
307 + 31466291 = 31466598
311 + 31466287 = 31466598

Showing the first eight; more decompositions exist.
