Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448312, here are decompositions:

3 + 31448309 = 31448312
13 + 31448299 = 31448312
19 + 31448293 = 31448312
31 + 31448281 = 31448312
79 + 31448233 = 31448312
151 + 31448161 = 31448312
163 + 31448149 = 31448312
241 + 31448071 = 31448312

Showing the first eight; more decompositions exist.
