Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609016, here are decompositions:

79 + 31608937 = 31609016
163 + 31608853 = 31609016
193 + 31608823 = 31609016
199 + 31608817 = 31609016
223 + 31608793 = 31609016
349 + 31608667 = 31609016
487 + 31608529 = 31609016
853 + 31608163 = 31609016

Showing the first eight; more decompositions exist.
