Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518304, here are decompositions:

3 + 31518301 = 31518304
17 + 31518287 = 31518304
23 + 31518281 = 31518304
107 + 31518197 = 31518304
131 + 31518173 = 31518304
281 + 31518023 = 31518304
353 + 31517951 = 31518304
443 + 31517861 = 31518304

Showing the first eight; more decompositions exist.
