Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601908, here are decompositions:

11 + 31601897 = 31601908
17 + 31601891 = 31601908
59 + 31601849 = 31601908
71 + 31601837 = 31601908
89 + 31601819 = 31601908
197 + 31601711 = 31601908
257 + 31601651 = 31601908
419 + 31601489 = 31601908

Showing the first eight; more decompositions exist.
