Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601824, here are decompositions:

5 + 31601819 = 31601824
41 + 31601783 = 31601824
101 + 31601723 = 31601824
113 + 31601711 = 31601824
173 + 31601651 = 31601824
257 + 31601567 = 31601824
311 + 31601513 = 31601824
431 + 31601393 = 31601824

Showing the first eight; more decompositions exist.
