Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105742, here are decompositions:

  • 41 + 105701 = 105742
  • 59 + 105683 = 105742
  • 89 + 105653 = 105742
  • 179 + 105563 = 105742
  • 233 + 105509 = 105742
  • 239 + 105503 = 105742
  • 251 + 105491 = 105742
  • 293 + 105449 = 105742

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 105.742 and was likely granted around 1870.

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