Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40506, here are decompositions:

7 + 40499 = 40506
13 + 40493 = 40506
19 + 40487 = 40506
23 + 40483 = 40506
47 + 40459 = 40506
73 + 40433 = 40506
79 + 40427 = 40506
83 + 40423 = 40506

Showing the first eight; more decompositions exist.
