Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105450, here are decompositions:

  • 13 + 105437 = 105450
  • 43 + 105407 = 105450
  • 53 + 105397 = 105450
  • 61 + 105389 = 105450
  • 71 + 105379 = 105450
  • 83 + 105367 = 105450
  • 89 + 105361 = 105450
  • 109 + 105341 = 105450

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 105,450 and was likely granted around 1870.

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