Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449006, here are decompositions:

19 + 31448987 = 31449006
97 + 31448909 = 31449006
103 + 31448903 = 31449006
107 + 31448899 = 31449006
109 + 31448897 = 31449006
167 + 31448839 = 31449006
293 + 31448713 = 31449006
307 + 31448699 = 31449006

Showing the first eight; more decompositions exist.
