Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179620, here are decompositions:

17 + 179603 = 179620
29 + 179591 = 179620
41 + 179579 = 179620
47 + 179573 = 179620
71 + 179549 = 179620
101 + 179519 = 179620
137 + 179483 = 179620
149 + 179471 = 179620

Showing the first eight; more decompositions exist.
