Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40824, here are decompositions:

5 + 40819 = 40824
11 + 40813 = 40824
23 + 40801 = 40824
37 + 40787 = 40824
53 + 40771 = 40824
61 + 40763 = 40824
73 + 40751 = 40824
127 + 40697 = 40824

Showing the first eight; more decompositions exist.
