Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609310, here are decompositions:

43 + 31609267 = 31609310
79 + 31609231 = 31609310
97 + 31609213 = 31609310
193 + 31609117 = 31609310
199 + 31609111 = 31609310
223 + 31609087 = 31609310
277 + 31609033 = 31609310
373 + 31608937 = 31609310

Showing the first eight; more decompositions exist.
