Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105408, here are decompositions:

  • 7 + 105401 = 105408
  • 11 + 105397 = 105408
  • 19 + 105389 = 105408
  • 29 + 105379 = 105408
  • 41 + 105367 = 105408
  • 47 + 105361 = 105408
  • 67 + 105341 = 105408
  • 71 + 105337 = 105408

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 105.408 and was likely granted around 1870.

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