Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40494, here are decompositions:

7 + 40487 = 40494
11 + 40483 = 40494
23 + 40471 = 40494
61 + 40433 = 40494
67 + 40427 = 40494
71 + 40423 = 40494
107 + 40387 = 40494
137 + 40357 = 40494

Showing the first eight; more decompositions exist.
