Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40536, here are decompositions:

5 + 40531 = 40536
7 + 40529 = 40536
17 + 40519 = 40536
29 + 40507 = 40536
37 + 40499 = 40536
43 + 40493 = 40536
53 + 40483 = 40536
103 + 40433 = 40536

Showing the first eight; more decompositions exist.
