Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518314, here are decompositions:

13 + 31518301 = 31518314
43 + 31518271 = 31518314
151 + 31518163 = 31518314
277 + 31518037 = 31518314
283 + 31518031 = 31518314
307 + 31518007 = 31518314
313 + 31518001 = 31518314
463 + 31517851 = 31518314

Showing the first eight; more decompositions exist.
