Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40804, here are decompositions:

3 + 40801 = 40804
17 + 40787 = 40804
41 + 40763 = 40804
53 + 40751 = 40804
107 + 40697 = 40804
167 + 40637 = 40804
227 + 40577 = 40804
311 + 40493 = 40804

Showing the first eight; more decompositions exist.
