Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449366, here are decompositions:

5 + 31449361 = 31449366
7 + 31449359 = 31449366
43 + 31449323 = 31449366
79 + 31449287 = 31449366
103 + 31449263 = 31449366
107 + 31449259 = 31449366
239 + 31449127 = 31449366
283 + 31449083 = 31449366

Showing the first eight; more decompositions exist.
