Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87384, here are decompositions:

47 + 87337 = 87384
61 + 87323 = 87384
67 + 87317 = 87384
71 + 87313 = 87384
103 + 87281 = 87384
107 + 87277 = 87384
127 + 87257 = 87384
131 + 87253 = 87384

Showing the first eight; more decompositions exist.
