Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477396, here are decompositions:

17 + 31477379 = 31477396
47 + 31477349 = 31477396
107 + 31477289 = 31477396
233 + 31477163 = 31477396
317 + 31477079 = 31477396
449 + 31476947 = 31477396
479 + 31476917 = 31477396
653 + 31476743 = 31477396

Showing the first eight; more decompositions exist.
