Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518376, here are decompositions:

23 + 31518353 = 31518376
47 + 31518329 = 31518376
89 + 31518287 = 31518376
137 + 31518239 = 31518376
167 + 31518209 = 31518376
179 + 31518197 = 31518376
353 + 31518023 = 31518376
467 + 31517909 = 31518376

Showing the first eight; more decompositions exist.
