Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471322, here are decompositions:

109 + 31471213 = 31471322
151 + 31471171 = 31471322
199 + 31471123 = 31471322
229 + 31471093 = 31471322
271 + 31471051 = 31471322
331 + 31470991 = 31471322
409 + 31470913 = 31471322
433 + 31470889 = 31471322

Showing the first eight; more decompositions exist.
