Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601946, here are decompositions:

23 + 31601923 = 31601946
73 + 31601873 = 31601946
83 + 31601863 = 31601946
97 + 31601849 = 31601946
109 + 31601837 = 31601946
127 + 31601819 = 31601946
137 + 31601809 = 31601946
163 + 31601783 = 31601946

Showing the first eight; more decompositions exist.
