Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179686, here are decompositions:

29 + 179657 = 179686
53 + 179633 = 179686
83 + 179603 = 179686
107 + 179579 = 179686
113 + 179573 = 179686
137 + 179549 = 179686
167 + 179519 = 179686
233 + 179453 = 179686

Showing the first eight; more decompositions exist.
