Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17670, here are decompositions:

11 + 17659 = 17670
13 + 17657 = 17670
43 + 17627 = 17670
47 + 17623 = 17670
61 + 17609 = 17670
71 + 17599 = 17670
73 + 17597 = 17670
89 + 17581 = 17670

Showing the first eight; more decompositions exist.
