Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103824, here are decompositions:

  • 11 + 103813 = 103824
  • 13 + 103811 = 103824
  • 23 + 103801 = 103824
  • 37 + 103787 = 103824
  • 101 + 103723 = 103824
  • 137 + 103687 = 103824
  • 167 + 103657 = 103824
  • 173 + 103651 = 103824

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 103,824 and was likely granted around 1870.

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