Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17806, here are decompositions:

17 + 17789 = 17806
23 + 17783 = 17806
59 + 17747 = 17806
137 + 17669 = 17806
149 + 17657 = 17806
179 + 17627 = 17806
197 + 17609 = 17806
227 + 17579 = 17806

Showing the first eight; more decompositions exist.
