Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17678, here are decompositions:

19 + 17659 = 17678
79 + 17599 = 17678
97 + 17581 = 17678
109 + 17569 = 17678
127 + 17551 = 17678
139 + 17539 = 17678
181 + 17497 = 17678
211 + 17467 = 17678

Showing the first eight; more decompositions exist.
