Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608716, here are decompositions:

3 + 31608713 = 31608716
19 + 31608697 = 31608716
127 + 31608589 = 31608716
367 + 31608349 = 31608716
379 + 31608337 = 31608716
397 + 31608319 = 31608716
499 + 31608217 = 31608716
547 + 31608169 = 31608716

Showing the first eight; more decompositions exist.
