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.
