Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105086, here are decompositions:

  • 67 + 105019 = 105086
  • 127 + 104959 = 105086
  • 139 + 104947 = 105086
  • 283 + 104803 = 105086
  • 307 + 104779 = 105086
  • 313 + 104773 = 105086
  • 379 + 104707 = 105086
  • 409 + 104677 = 105086

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 105,086 and was likely granted around 1870.

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