Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477568, here are decompositions:

7 + 31477561 = 31477568
19 + 31477549 = 31477568
61 + 31477507 = 31477568
139 + 31477429 = 31477568
277 + 31477291 = 31477568
457 + 31477111 = 31477568
541 + 31477027 = 31477568
547 + 31477021 = 31477568

Showing the first eight; more decompositions exist.
