Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609712, here are decompositions:

19 + 31609693 = 31609712
103 + 31609609 = 31609712
151 + 31609561 = 31609712
163 + 31609549 = 31609712
181 + 31609531 = 31609712
193 + 31609519 = 31609712
331 + 31609381 = 31609712
373 + 31609339 = 31609712

Showing the first eight; more decompositions exist.
