Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101742, here are decompositions:

  • 5 + 101737 = 101742
  • 19 + 101723 = 101742
  • 23 + 101719 = 101742
  • 41 + 101701 = 101742
  • 61 + 101681 = 101742
  • 79 + 101663 = 101742
  • 89 + 101653 = 101742
  • 101 + 101641 = 101742

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 101,742 and was likely granted around 1870.

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