Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40836, here are decompositions:

7 + 40829 = 40836
13 + 40823 = 40836
17 + 40819 = 40836
23 + 40813 = 40836
73 + 40763 = 40836
97 + 40739 = 40836
127 + 40709 = 40836
137 + 40699 = 40836

Showing the first eight; more decompositions exist.
