Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530096, here are decompositions:

53 + 31530043 = 31530096
67 + 31530029 = 31530096
79 + 31530017 = 31530096
127 + 31529969 = 31530096
163 + 31529933 = 31530096
173 + 31529923 = 31530096
197 + 31529899 = 31530096
277 + 31529819 = 31530096

Showing the first eight; more decompositions exist.
