Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40512, here are decompositions:

5 + 40507 = 40512
13 + 40499 = 40512
19 + 40493 = 40512
29 + 40483 = 40512
41 + 40471 = 40512
53 + 40459 = 40512
79 + 40433 = 40512
83 + 40429 = 40512

Showing the first eight; more decompositions exist.
