Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601910, here are decompositions:

13 + 31601897 = 31601910
19 + 31601891 = 31601910
29 + 31601881 = 31601910
37 + 31601873 = 31601910
47 + 31601863 = 31601910
61 + 31601849 = 31601910
73 + 31601837 = 31601910
101 + 31601809 = 31601910

Showing the first eight; more decompositions exist.
