Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609004, here are decompositions:

67 + 31608937 = 31609004
151 + 31608853 = 31609004
181 + 31608823 = 31609004
211 + 31608793 = 31609004
277 + 31608727 = 31609004
283 + 31608721 = 31609004
307 + 31608697 = 31609004
337 + 31608667 = 31609004

Showing the first eight; more decompositions exist.
