Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102384, here are decompositions:

  • 17 + 102367 = 102384
  • 47 + 102337 = 102384
  • 67 + 102317 = 102384
  • 83 + 102301 = 102384
  • 131 + 102253 = 102384
  • 151 + 102233 = 102384
  • 167 + 102217 = 102384
  • 181 + 102203 = 102384

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 102,384 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
