Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484328, here are decompositions:

11 + 31484317 = 31484328
47 + 31484281 = 31484328
61 + 31484267 = 31484328
89 + 31484239 = 31484328
149 + 31484179 = 31484328
151 + 31484177 = 31484328
167 + 31484161 = 31484328
199 + 31484129 = 31484328

Showing the first eight; more decompositions exist.
