Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484358, here are decompositions:

5 + 31484353 = 31484358
19 + 31484339 = 31484358
41 + 31484317 = 31484358
149 + 31484209 = 31484358
151 + 31484207 = 31484358
179 + 31484179 = 31484358
181 + 31484177 = 31484358
197 + 31484161 = 31484358

Showing the first eight; more decompositions exist.
