Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17788, here are decompositions:

5 + 17783 = 17788
41 + 17747 = 17788
59 + 17729 = 17788
107 + 17681 = 17788
131 + 17657 = 17788
179 + 17609 = 17788
191 + 17597 = 17788
269 + 17519 = 17788

Showing the first eight; more decompositions exist.
