Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609284, here are decompositions:

17 + 31609267 = 31609284
53 + 31609231 = 31609284
61 + 31609223 = 31609284
71 + 31609213 = 31609284
167 + 31609117 = 31609284
173 + 31609111 = 31609284
191 + 31609093 = 31609284
193 + 31609091 = 31609284

Showing the first eight; more decompositions exist.
