Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17786, here are decompositions:

3 + 17783 = 17786
37 + 17749 = 17786
73 + 17713 = 17786
79 + 17707 = 17786
103 + 17683 = 17786
127 + 17659 = 17786
163 + 17623 = 17786
277 + 17509 = 17786

Showing the first eight; more decompositions exist.
