Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477346, here are decompositions:

139 + 31477207 = 31477346
283 + 31477063 = 31477346
499 + 31476847 = 31477346
547 + 31476799 = 31477346
613 + 31476733 = 31477346
619 + 31476727 = 31477346
643 + 31476703 = 31477346
739 + 31476607 = 31477346

Showing the first eight; more decompositions exist.
