Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40866, here are decompositions:

13 + 40853 = 40866
17 + 40849 = 40866
19 + 40847 = 40866
37 + 40829 = 40866
43 + 40823 = 40866
47 + 40819 = 40866
53 + 40813 = 40866
79 + 40787 = 40866

Showing the first eight; more decompositions exist.
