Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102874, here are decompositions:

  • 3 + 102871 = 102874
  • 113 + 102761 = 102874
  • 173 + 102701 = 102874
  • 197 + 102677 = 102874
  • 227 + 102647 = 102874
  • 263 + 102611 = 102874
  • 281 + 102593 = 102874
  • 311 + 102563 = 102874

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 102,874 and was likely granted around 1870.

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