Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477798, here are decompositions:

5 + 31477793 = 31477798
17 + 31477781 = 31477798
47 + 31477751 = 31477798
101 + 31477697 = 31477798
227 + 31477571 = 31477798
419 + 31477379 = 31477798
449 + 31477349 = 31477798
509 + 31477289 = 31477798

Showing the first eight; more decompositions exist.
