Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449046, here are decompositions:

3 + 31449043 = 31449046
17 + 31449029 = 31449046
29 + 31449017 = 31449046
59 + 31448987 = 31449046
137 + 31448909 = 31449046
149 + 31448897 = 31449046
347 + 31448699 = 31449046
353 + 31448693 = 31449046

Showing the first eight; more decompositions exist.
