Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17766, here are decompositions:

5 + 17761 = 17766
17 + 17749 = 17766
19 + 17747 = 17766
29 + 17737 = 17766
37 + 17729 = 17766
53 + 17713 = 17766
59 + 17707 = 17766
83 + 17683 = 17766

Showing the first eight; more decompositions exist.
