Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186742, here are decompositions:

  • 41 + 186701 = 186742
  • 53 + 186689 = 186742
  • 71 + 186671 = 186742
  • 89 + 186653 = 186742
  • 113 + 186629 = 186742
  • 173 + 186569 = 186742
  • 191 + 186551 = 186742
  • 263 + 186479 = 186742

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 186,742 and was likely granted around 1875.

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