Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488108, here are decompositions:

7 + 31488101 = 31488108
17 + 31488091 = 31488108
19 + 31488089 = 31488108
37 + 31488071 = 31488108
89 + 31488019 = 31488108
131 + 31487977 = 31488108
151 + 31487957 = 31488108
167 + 31487941 = 31488108

Showing the first eight; more decompositions exist.
