Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179388, here are decompositions:

5 + 179383 = 179388
7 + 179381 = 179388
19 + 179369 = 179388
31 + 179357 = 179388
37 + 179351 = 179388
61 + 179327 = 179388
67 + 179321 = 179388
71 + 179317 = 179388

Showing the first eight; more decompositions exist.
