Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449016, here are decompositions:

29 + 31448987 = 31449016
107 + 31448909 = 31449016
113 + 31448903 = 31449016
317 + 31448699 = 31449016
509 + 31448507 = 31449016
569 + 31448447 = 31449016
593 + 31448423 = 31449016
647 + 31448369 = 31449016

Showing the first eight; more decompositions exist.
