Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519096, here are decompositions:

5 + 31519091 = 31519096
23 + 31519073 = 31519096
29 + 31519067 = 31519096
47 + 31519049 = 31519096
107 + 31518989 = 31519096
173 + 31518923 = 31519096
197 + 31518899 = 31519096
227 + 31518869 = 31519096

Showing the first eight; more decompositions exist.
