Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448716, here are decompositions:

3 + 31448713 = 31448716
17 + 31448699 = 31448716
23 + 31448693 = 31448716
113 + 31448603 = 31448716
137 + 31448579 = 31448716
197 + 31448519 = 31448716
269 + 31448447 = 31448716
293 + 31448423 = 31448716

Showing the first eight; more decompositions exist.
