Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40530, here are decompositions:

11 + 40519 = 40530
23 + 40507 = 40530
31 + 40499 = 40530
37 + 40493 = 40530
43 + 40487 = 40530
47 + 40483 = 40530
59 + 40471 = 40530
71 + 40459 = 40530

Showing the first eight; more decompositions exist.
