Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105000, here are decompositions:

  • 13 + 104987 = 105000
  • 29 + 104971 = 105000
  • 41 + 104959 = 105000
  • 47 + 104953 = 105000
  • 53 + 104947 = 105000
  • 67 + 104933 = 105000
  • 83 + 104917 = 105000
  • 89 + 104911 = 105000

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 105,000 and was likely granted around 1870.

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