Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105938, here are decompositions:

  • 31 + 105907 = 105938
  • 67 + 105871 = 105938
  • 109 + 105829 = 105938
  • 211 + 105727 = 105938
  • 271 + 105667 = 105938
  • 331 + 105607 = 105938
  • 337 + 105601 = 105938
  • 397 + 105541 = 105938

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 105,938 and was likely granted around 1870.

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