Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610234, here are decompositions:

3 + 31610231 = 31610234
37 + 31610197 = 31610234
127 + 31610107 = 31610234
151 + 31610083 = 31610234
211 + 31610023 = 31610234
223 + 31610011 = 31610234
241 + 31609993 = 31610234
277 + 31609957 = 31610234

Showing the first eight; more decompositions exist.
