Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179680, here are decompositions:

23 + 179657 = 179680
29 + 179651 = 179680
47 + 179633 = 179680
89 + 179591 = 179680
101 + 179579 = 179680
107 + 179573 = 179680
131 + 179549 = 179680
197 + 179483 = 179680

Showing the first eight; more decompositions exist.
