Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608962, here are decompositions:

3 + 31608959 = 31608962
79 + 31608883 = 31608962
109 + 31608853 = 31608962
139 + 31608823 = 31608962
241 + 31608721 = 31608962
373 + 31608589 = 31608962
433 + 31608529 = 31608962
613 + 31608349 = 31608962

Showing the first eight; more decompositions exist.
