Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477566, here are decompositions:

5 + 31477561 = 31477566
13 + 31477553 = 31477566
17 + 31477549 = 31477566
23 + 31477543 = 31477566
53 + 31477513 = 31477566
59 + 31477507 = 31477566
83 + 31477483 = 31477566
137 + 31477429 = 31477566

Showing the first eight; more decompositions exist.
