Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608796, here are decompositions:

3 + 31608793 = 31608796
17 + 31608779 = 31608796
47 + 31608749 = 31608796
59 + 31608737 = 31608796
83 + 31608713 = 31608796
269 + 31608527 = 31608796
347 + 31608449 = 31608796
647 + 31608149 = 31608796

Showing the first eight; more decompositions exist.
