Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17768, here are decompositions:

7 + 17761 = 17768
19 + 17749 = 17768
31 + 17737 = 17768
61 + 17707 = 17768
109 + 17659 = 17768
199 + 17569 = 17768
229 + 17539 = 17768
271 + 17497 = 17768

Showing the first eight; more decompositions exist.
