Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179380, here are decompositions:

11 + 179369 = 179380
23 + 179357 = 179380
29 + 179351 = 179380
53 + 179327 = 179380
59 + 179321 = 179380
137 + 179243 = 179380
167 + 179213 = 179380
269 + 179111 = 179380

Showing the first eight; more decompositions exist.
