Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179688, here are decompositions:

17 + 179671 = 179688
29 + 179659 = 179688
31 + 179657 = 179688
37 + 179651 = 179688
97 + 179591 = 179688
107 + 179581 = 179688
109 + 179579 = 179688
139 + 179549 = 179688

Showing the first eight; more decompositions exist.
