Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448304, here are decompositions:

5 + 31448299 = 31448304
7 + 31448297 = 31448304
11 + 31448293 = 31448304
23 + 31448281 = 31448304
71 + 31448233 = 31448304
103 + 31448201 = 31448304
113 + 31448191 = 31448304
163 + 31448141 = 31448304

Showing the first eight; more decompositions exist.
