Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609796, here are decompositions:

3 + 31609793 = 31609796
19 + 31609777 = 31609796
37 + 31609759 = 31609796
73 + 31609723 = 31609796
103 + 31609693 = 31609796
277 + 31609519 = 31609796
457 + 31609339 = 31609796
607 + 31609189 = 31609796

Showing the first eight; more decompositions exist.
