Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449010, here are decompositions:

23 + 31448987 = 31449010
101 + 31448909 = 31449010
107 + 31448903 = 31449010
113 + 31448897 = 31449010
269 + 31448741 = 31449010
293 + 31448717 = 31449010
311 + 31448699 = 31449010
317 + 31448693 = 31449010

Showing the first eight; more decompositions exist.
