Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105432, here are decompositions:

  • 31 + 105401 = 105432
  • 43 + 105389 = 105432
  • 53 + 105379 = 105432
  • 59 + 105373 = 105432
  • 71 + 105361 = 105432
  • 73 + 105359 = 105432
  • 101 + 105331 = 105432
  • 109 + 105323 = 105432

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 105,432 and was likely granted around 1870.

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