Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609046, here are decompositions:

13 + 31609033 = 31609046
109 + 31608937 = 31609046
163 + 31608883 = 31609046
193 + 31608853 = 31609046
223 + 31608823 = 31609046
229 + 31608817 = 31609046
349 + 31608697 = 31609046
379 + 31608667 = 31609046

Showing the first eight; more decompositions exist.
