Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609458, here are decompositions:

5 + 31609453 = 31609458
7 + 31609451 = 31609458
191 + 31609267 = 31609458
227 + 31609231 = 31609458
229 + 31609229 = 31609458
269 + 31609189 = 31609458
347 + 31609111 = 31609458
367 + 31609091 = 31609458

Showing the first eight; more decompositions exist.
