Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105122, here are decompositions:

  • 103 + 105019 = 105122
  • 151 + 104971 = 105122
  • 163 + 104959 = 105122
  • 211 + 104911 = 105122
  • 271 + 104851 = 105122
  • 349 + 104773 = 105122
  • 379 + 104743 = 105122
  • 421 + 104701 = 105122

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 105,122 and was likely granted around 1870.

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