Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105256, here are decompositions:

  • 3 + 105253 = 105256
  • 5 + 105251 = 105256
  • 17 + 105239 = 105256
  • 29 + 105227 = 105256
  • 83 + 105173 = 105256
  • 89 + 105167 = 105256
  • 113 + 105143 = 105256
  • 149 + 105107 = 105256

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 105,256 and was likely granted around 1870.

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