Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488096, here are decompositions:

5 + 31488091 = 31488096
7 + 31488089 = 31488096
37 + 31488059 = 31488096
43 + 31488053 = 31488096
83 + 31488013 = 31488096
103 + 31487993 = 31488096
139 + 31487957 = 31488096
179 + 31487917 = 31488096

Showing the first eight; more decompositions exist.
