Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172384, here are decompositions:

11 + 172373 = 172384
41 + 172343 = 172384
53 + 172331 = 172384
71 + 172313 = 172384
101 + 172283 = 172384
167 + 172217 = 172384
227 + 172157 = 172384
257 + 172127 = 172384

Showing the first eight; more decompositions exist.
