Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448914, here are decompositions:

5 + 31448909 = 31448914
11 + 31448903 = 31448914
17 + 31448897 = 31448914
23 + 31448891 = 31448914
173 + 31448741 = 31448914
197 + 31448717 = 31448914
293 + 31448621 = 31448914
311 + 31448603 = 31448914

Showing the first eight; more decompositions exist.
