Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484306, here are decompositions:

3 + 31484303 = 31484306
67 + 31484239 = 31484306
97 + 31484209 = 31484306
103 + 31484203 = 31484306
127 + 31484179 = 31484306
163 + 31484143 = 31484306
349 + 31483957 = 31484306
379 + 31483927 = 31484306

Showing the first eight; more decompositions exist.
