Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601848, here are decompositions:

11 + 31601837 = 31601848
29 + 31601819 = 31601848
137 + 31601711 = 31601848
149 + 31601699 = 31601848
197 + 31601651 = 31601848
281 + 31601567 = 31601848
359 + 31601489 = 31601848
431 + 31601417 = 31601848

Showing the first eight; more decompositions exist.
