Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519056, here are decompositions:

7 + 31519049 = 31519056
67 + 31518989 = 31519056
103 + 31518953 = 31519056
157 + 31518899 = 31519056
193 + 31518863 = 31519056
197 + 31518859 = 31519056
229 + 31518827 = 31519056
263 + 31518793 = 31519056

Showing the first eight; more decompositions exist.
