Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477582, here are decompositions:

5 + 31477577 = 31477582
11 + 31477571 = 31477582
29 + 31477553 = 31477582
233 + 31477349 = 31477582
281 + 31477301 = 31477582
293 + 31477289 = 31477582
401 + 31477181 = 31477582
419 + 31477163 = 31477582

Showing the first eight; more decompositions exist.
