Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466322, here are decompositions:

31 + 31466291 = 31466322
59 + 31466263 = 31466322
71 + 31466251 = 31466322
73 + 31466249 = 31466322
89 + 31466233 = 31466322
101 + 31466221 = 31466322
149 + 31466173 = 31466322
179 + 31466143 = 31466322

Showing the first eight; more decompositions exist.
