Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101000, here are decompositions:

  • 13 + 100987 = 101000
  • 19 + 100981 = 101000
  • 43 + 100957 = 101000
  • 73 + 100927 = 101000
  • 199 + 100801 = 101000
  • 307 + 100693 = 101000
  • 331 + 100669 = 101000
  • 379 + 100621 = 101000

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 101,000 and was likely granted around 1870.

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