Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448444, here are decompositions:

31 + 31448413 = 31448444
67 + 31448377 = 31448444
151 + 31448293 = 31448444
163 + 31448281 = 31448444
211 + 31448233 = 31448444
283 + 31448161 = 31448444
373 + 31448071 = 31448444
421 + 31448023 = 31448444

Showing the first eight; more decompositions exist.
