Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104742, here are decompositions:

  • 13 + 104729 = 104742
  • 19 + 104723 = 104742
  • 31 + 104711 = 104742
  • 41 + 104701 = 104742
  • 59 + 104683 = 104742
  • 61 + 104681 = 104742
  • 83 + 104659 = 104742
  • 103 + 104639 = 104742

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 104,742 and was likely granted around 1870.

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