Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477106, here are decompositions:

7 + 31477099 = 31477106
43 + 31477063 = 31477106
79 + 31477027 = 31477106
277 + 31476829 = 31477106
307 + 31476799 = 31477106
373 + 31476733 = 31477106
379 + 31476727 = 31477106
499 + 31476607 = 31477106

Showing the first eight; more decompositions exist.
