Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609106, here are decompositions:

13 + 31609093 = 31609106
19 + 31609087 = 31609106
73 + 31609033 = 31609106
223 + 31608883 = 31609106
283 + 31608823 = 31609106
313 + 31608793 = 31609106
349 + 31608757 = 31609106
379 + 31608727 = 31609106

Showing the first eight; more decompositions exist.
