Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519934, here are decompositions:

7 + 31519927 = 31519934
97 + 31519837 = 31519934
151 + 31519783 = 31519934
181 + 31519753 = 31519934
223 + 31519711 = 31519934
367 + 31519567 = 31519934
571 + 31519363 = 31519934
577 + 31519357 = 31519934

Showing the first eight; more decompositions exist.
