Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101856, here are decompositions:

  • 17 + 101839 = 101856
  • 19 + 101837 = 101856
  • 23 + 101833 = 101856
  • 59 + 101797 = 101856
  • 67 + 101789 = 101856
  • 107 + 101749 = 101856
  • 109 + 101747 = 101856
  • 137 + 101719 = 101856

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 101,856 and was likely granted around 1870.

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