Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40518, here are decompositions:

11 + 40507 = 40518
19 + 40499 = 40518
31 + 40487 = 40518
47 + 40471 = 40518
59 + 40459 = 40518
89 + 40429 = 40518
131 + 40387 = 40518
157 + 40361 = 40518

Showing the first eight; more decompositions exist.
