Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601884, here are decompositions:

3 + 31601881 = 31601884
11 + 31601873 = 31601884
47 + 31601837 = 31601884
101 + 31601783 = 31601884
173 + 31601711 = 31601884
233 + 31601651 = 31601884
317 + 31601567 = 31601884
467 + 31601417 = 31601884

Showing the first eight; more decompositions exist.
