Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609254, here are decompositions:

23 + 31609231 = 31609254
31 + 31609223 = 31609254
41 + 31609213 = 31609254
137 + 31609117 = 31609254
163 + 31609091 = 31609254
167 + 31609087 = 31609254
223 + 31609031 = 31609254
283 + 31608971 = 31609254

Showing the first eight; more decompositions exist.
