Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449198, here are decompositions:

7 + 31449191 = 31449198
19 + 31449179 = 31449198
71 + 31449127 = 31449198
127 + 31449071 = 31449198
181 + 31449017 = 31449198
211 + 31448987 = 31449198
307 + 31448891 = 31449198
359 + 31448839 = 31449198

Showing the first eight; more decompositions exist.
