Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448544, here are decompositions:

11 + 31448533 = 31448544
37 + 31448507 = 31448544
97 + 31448447 = 31448544
131 + 31448413 = 31448544
163 + 31448381 = 31448544
167 + 31448377 = 31448544
223 + 31448321 = 31448544
241 + 31448303 = 31448544

Showing the first eight; more decompositions exist.
