Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17706, here are decompositions:

23 + 17683 = 17706
37 + 17669 = 17706
47 + 17659 = 17706
79 + 17627 = 17706
83 + 17623 = 17706
97 + 17609 = 17706
107 + 17599 = 17706
109 + 17597 = 17706

Showing the first eight; more decompositions exist.
