Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609350, here are decompositions:

11 + 31609339 = 31609350
61 + 31609289 = 31609350
83 + 31609267 = 31609350
127 + 31609223 = 31609350
137 + 31609213 = 31609350
233 + 31609117 = 31609350
239 + 31609111 = 31609350
257 + 31609093 = 31609350

Showing the first eight; more decompositions exist.
