Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104890, here are decompositions:

  • 11 + 104879 = 104890
  • 41 + 104849 = 104890
  • 59 + 104831 = 104890
  • 89 + 104801 = 104890
  • 101 + 104789 = 104890
  • 131 + 104759 = 104890
  • 167 + 104723 = 104890
  • 173 + 104717 = 104890

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 104,890 and was likely granted around 1870.

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