Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608752, here are decompositions:

3 + 31608749 = 31608752
31 + 31608721 = 31608752
163 + 31608589 = 31608752
223 + 31608529 = 31608752
271 + 31608481 = 31608752
433 + 31608319 = 31608752
619 + 31608133 = 31608752
661 + 31608091 = 31608752

Showing the first eight; more decompositions exist.
