Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608744, here are decompositions:

7 + 31608737 = 31608744
17 + 31608727 = 31608744
23 + 31608721 = 31608744
31 + 31608713 = 31608744
47 + 31608697 = 31608744
157 + 31608587 = 31608744
263 + 31608481 = 31608744
317 + 31608427 = 31608744

Showing the first eight; more decompositions exist.
