Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104842, here are decompositions:

  • 11 + 104831 = 104842
  • 41 + 104801 = 104842
  • 53 + 104789 = 104842
  • 83 + 104759 = 104842
  • 113 + 104729 = 104842
  • 131 + 104711 = 104842
  • 149 + 104693 = 104842
  • 191 + 104651 = 104842

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 104,842 and was likely granted around 1870.

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