Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471366, here are decompositions:

5 + 31471361 = 31471366
149 + 31471217 = 31471366
257 + 31471109 = 31471366
359 + 31471007 = 31471366
389 + 31470977 = 31471366
449 + 31470917 = 31471366
503 + 31470863 = 31471366
743 + 31470623 = 31471366

Showing the first eight; more decompositions exist.
