Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179640, here are decompositions:

7 + 179633 = 179640
17 + 179623 = 179640
37 + 179603 = 179640
47 + 179593 = 179640
59 + 179581 = 179640
61 + 179579 = 179640
67 + 179573 = 179640
107 + 179533 = 179640

Showing the first eight; more decompositions exist.
