Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448926, here are decompositions:

17 + 31448909 = 31448926
23 + 31448903 = 31448926
29 + 31448897 = 31448926
227 + 31448699 = 31448926
233 + 31448693 = 31448926
347 + 31448579 = 31448926
419 + 31448507 = 31448926
479 + 31448447 = 31448926

Showing the first eight; more decompositions exist.
