Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170768, here are decompositions:

  • 7 + 170761 = 170768
  • 19 + 170749 = 170768
  • 61 + 170707 = 170768
  • 67 + 170701 = 170768
  • 79 + 170689 = 170768
  • 127 + 170641 = 170768
  • 211 + 170557 = 170768
  • 229 + 170539 = 170768

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 170,768 and was likely granted around 1874.

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