Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466622, here are decompositions:

59 + 31466563 = 31466622
73 + 31466549 = 31466622
233 + 31466389 = 31466622
241 + 31466381 = 31466622
281 + 31466341 = 31466622
293 + 31466329 = 31466622
331 + 31466291 = 31466622
359 + 31466263 = 31466622

Showing the first eight; more decompositions exist.
