Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105982, here are decompositions:

  • 5 + 105977 = 105982
  • 11 + 105971 = 105982
  • 29 + 105953 = 105982
  • 53 + 105929 = 105982
  • 83 + 105899 = 105982
  • 281 + 105701 = 105982
  • 419 + 105563 = 105982
  • 449 + 105533 = 105982

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 105 982 and was likely granted around 1870.

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