Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477610, here are decompositions:

7 + 31477603 = 31477610
61 + 31477549 = 31477610
67 + 31477543 = 31477610
97 + 31477513 = 31477610
103 + 31477507 = 31477610
127 + 31477483 = 31477610
163 + 31477447 = 31477610
181 + 31477429 = 31477610

Showing the first eight; more decompositions exist.
