Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449174, here are decompositions:

11 + 31449163 = 31449174
47 + 31449127 = 31449174
103 + 31449071 = 31449174
131 + 31449043 = 31449174
137 + 31449037 = 31449174
157 + 31449017 = 31449174
271 + 31448903 = 31449174
277 + 31448897 = 31449174

Showing the first eight; more decompositions exist.
