Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180384, here are decompositions:

5 + 180379 = 180384
13 + 180371 = 180384
23 + 180361 = 180384
37 + 180347 = 180384
47 + 180337 = 180384
53 + 180331 = 180384
67 + 180317 = 180384
73 + 180311 = 180384

Showing the first eight; more decompositions exist.
