Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179660, here are decompositions:

3 + 179657 = 179660
37 + 179623 = 179660
67 + 179593 = 179660
79 + 179581 = 179660
97 + 179563 = 179660
127 + 179533 = 179660
163 + 179497 = 179660
181 + 179479 = 179660

Showing the first eight; more decompositions exist.
