Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173680, here are decompositions:

11 + 173669 = 173680
29 + 173651 = 173680
107 + 173573 = 173680
131 + 173549 = 173680
137 + 173543 = 173680
149 + 173531 = 173680
179 + 173501 = 173680
197 + 173483 = 173680

Showing the first eight; more decompositions exist.
