Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488024, here are decompositions:

5 + 31488019 = 31488024
11 + 31488013 = 31488024
31 + 31487993 = 31488024
47 + 31487977 = 31488024
67 + 31487957 = 31488024
83 + 31487941 = 31488024
107 + 31487917 = 31488024
151 + 31487873 = 31488024

Showing the first eight; more decompositions exist.
