Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609604, here are decompositions:

43 + 31609561 = 31609604
73 + 31609531 = 31609604
151 + 31609453 = 31609604
211 + 31609393 = 31609604
223 + 31609381 = 31609604
337 + 31609267 = 31609604
373 + 31609231 = 31609604
487 + 31609117 = 31609604

Showing the first eight; more decompositions exist.
