Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104870, here are decompositions:

  • 19 + 104851 = 104870
  • 43 + 104827 = 104870
  • 67 + 104803 = 104870
  • 97 + 104773 = 104870
  • 109 + 104761 = 104870
  • 127 + 104743 = 104870
  • 163 + 104707 = 104870
  • 193 + 104677 = 104870

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 104,870 and was likely granted around 1870.

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