Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609034, here are decompositions:

3 + 31609031 = 31609034
97 + 31608937 = 31609034
151 + 31608883 = 31609034
181 + 31608853 = 31609034
211 + 31608823 = 31609034
241 + 31608793 = 31609034
277 + 31608757 = 31609034
307 + 31608727 = 31609034

Showing the first eight; more decompositions exist.
