Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40470, here are decompositions:

11 + 40459 = 40470
37 + 40433 = 40470
41 + 40429 = 40470
43 + 40427 = 40470
47 + 40423 = 40470
83 + 40387 = 40470
109 + 40361 = 40470
113 + 40357 = 40470

Showing the first eight; more decompositions exist.
