Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100928, here are decompositions:

  • 127 + 100801 = 100928
  • 181 + 100747 = 100928
  • 229 + 100699 = 100928
  • 307 + 100621 = 100928
  • 337 + 100591 = 100928
  • 379 + 100549 = 100928
  • 409 + 100519 = 100928
  • 571 + 100357 = 100928

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 100,928 and was likely granted around 1870.

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