Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106640, here are decompositions:

  • 3 + 106637 = 106640
  • 13 + 106627 = 106640
  • 19 + 106621 = 106640
  • 97 + 106543 = 106640
  • 103 + 106537 = 106640
  • 109 + 106531 = 106640
  • 139 + 106501 = 106640
  • 199 + 106441 = 106640

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 106,640 and was likely granted around 1870.

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