Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17836, here are decompositions:

29 + 17807 = 17836
47 + 17789 = 17836
53 + 17783 = 17836
89 + 17747 = 17836
107 + 17729 = 17836
167 + 17669 = 17836
179 + 17657 = 17836
227 + 17609 = 17836

Showing the first eight; more decompositions exist.
