Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601904, here are decompositions:

7 + 31601897 = 31601904
13 + 31601891 = 31601904
23 + 31601881 = 31601904
31 + 31601873 = 31601904
41 + 31601863 = 31601904
67 + 31601837 = 31601904
137 + 31601767 = 31601904
181 + 31601723 = 31601904

Showing the first eight; more decompositions exist.
