Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135724, here are decompositions:

  • 3 + 135721 = 135724
  • 5 + 135719 = 135724
  • 23 + 135701 = 135724
  • 53 + 135671 = 135724
  • 101 + 135623 = 135724
  • 107 + 135617 = 135724
  • 131 + 135593 = 135724
  • 191 + 135533 = 135724

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 135,724 and was likely granted around 1872.

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