Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448328, here are decompositions:

5 + 31448323 = 31448328
7 + 31448321 = 31448328
19 + 31448309 = 31448328
29 + 31448299 = 31448328
31 + 31448297 = 31448328
47 + 31448281 = 31448328
127 + 31448201 = 31448328
137 + 31448191 = 31448328

Showing the first eight; more decompositions exist.
