Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609844, here are decompositions:

31 + 31609813 = 31609844
67 + 31609777 = 31609844
103 + 31609741 = 31609844
151 + 31609693 = 31609844
283 + 31609561 = 31609844
313 + 31609531 = 31609844
463 + 31609381 = 31609844
577 + 31609267 = 31609844

Showing the first eight; more decompositions exist.
