Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477376, here are decompositions:

163 + 31477213 = 31477376
277 + 31477099 = 31477376
313 + 31477063 = 31477376
349 + 31477027 = 31477376
523 + 31476853 = 31477376
547 + 31476829 = 31477376
577 + 31476799 = 31477376
643 + 31476733 = 31477376

Showing the first eight; more decompositions exist.
