Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471346, here are decompositions:

139 + 31471207 = 31471346
199 + 31471147 = 31471346
223 + 31471123 = 31471346
349 + 31470997 = 31471346
433 + 31470913 = 31471346
457 + 31470889 = 31471346
499 + 31470847 = 31471346
523 + 31470823 = 31471346

Showing the first eight; more decompositions exist.
