Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179966, here are decompositions:

13 + 179953 = 179966
19 + 179947 = 179966
43 + 179923 = 179966
67 + 179899 = 179966
139 + 179827 = 179966
223 + 179743 = 179966
229 + 179737 = 179966
277 + 179689 = 179966

Showing the first eight; more decompositions exist.
