Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40542, here are decompositions:

11 + 40531 = 40542
13 + 40529 = 40542
23 + 40519 = 40542
43 + 40499 = 40542
59 + 40483 = 40542
71 + 40471 = 40542
83 + 40459 = 40542
109 + 40433 = 40542

Showing the first eight; more decompositions exist.
