Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608852, here are decompositions:

29 + 31608823 = 31608852
31 + 31608821 = 31608852
59 + 31608793 = 31608852
73 + 31608779 = 31608852
103 + 31608749 = 31608852
131 + 31608721 = 31608852
139 + 31608713 = 31608852
263 + 31608589 = 31608852

Showing the first eight; more decompositions exist.
