Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606928, here are decompositions:

271 + 31606657 = 31606928
277 + 31606651 = 31606928
349 + 31606579 = 31606928
499 + 31606429 = 31606928
541 + 31606387 = 31606928
547 + 31606381 = 31606928
631 + 31606297 = 31606928
877 + 31606051 = 31606928

Showing the first eight; more decompositions exist.
