Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179664, here are decompositions:

5 + 179659 = 179664
7 + 179657 = 179664
13 + 179651 = 179664
31 + 179633 = 179664
41 + 179623 = 179664
61 + 179603 = 179664
71 + 179593 = 179664
73 + 179591 = 179664

Showing the first eight; more decompositions exist.
