Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477670, here are decompositions:

13 + 31477657 = 31477670
67 + 31477603 = 31477670
109 + 31477561 = 31477670
127 + 31477543 = 31477670
157 + 31477513 = 31477670
163 + 31477507 = 31477670
223 + 31477447 = 31477670
241 + 31477429 = 31477670

Showing the first eight; more decompositions exist.
