Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609334, here are decompositions:

67 + 31609267 = 31609334
103 + 31609231 = 31609334
223 + 31609111 = 31609334
241 + 31609093 = 31609334
397 + 31608937 = 31609334
541 + 31608793 = 31609334
577 + 31608757 = 31609334
607 + 31608727 = 31609334

Showing the first eight; more decompositions exist.
