Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518276, here are decompositions:

5 + 31518271 = 31518276
17 + 31518259 = 31518276
37 + 31518239 = 31518276
47 + 31518229 = 31518276
67 + 31518209 = 31518276
79 + 31518197 = 31518276
103 + 31518173 = 31518276
113 + 31518163 = 31518276

Showing the first eight; more decompositions exist.
