Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609794, here are decompositions:

17 + 31609777 = 31609794
53 + 31609741 = 31609794
71 + 31609723 = 31609794
101 + 31609693 = 31609794
103 + 31609691 = 31609794
163 + 31609631 = 31609794
211 + 31609583 = 31609794
233 + 31609561 = 31609794

Showing the first eight; more decompositions exist.
