Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609824, here are decompositions:

5 + 31609819 = 31609824
11 + 31609813 = 31609824
31 + 31609793 = 31609824
47 + 31609777 = 31609824
83 + 31609741 = 31609824
101 + 31609723 = 31609824
131 + 31609693 = 31609824
163 + 31609661 = 31609824

Showing the first eight; more decompositions exist.
