Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448484, here are decompositions:

5 + 31448479 = 31448484
37 + 31448447 = 31448484
61 + 31448423 = 31448484
71 + 31448413 = 31448484
103 + 31448381 = 31448484
107 + 31448377 = 31448484
163 + 31448321 = 31448484
181 + 31448303 = 31448484

Showing the first eight; more decompositions exist.
