Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67866, here are decompositions:

13 + 67853 = 67866
23 + 67843 = 67866
37 + 67829 = 67866
47 + 67819 = 67866
59 + 67807 = 67866
83 + 67783 = 67866
89 + 67777 = 67866
103 + 67763 = 67866

Showing the first eight; more decompositions exist.
