Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102000, here are decompositions:

  • 13 + 101987 = 102000
  • 23 + 101977 = 102000
  • 37 + 101963 = 102000
  • 43 + 101957 = 102000
  • 61 + 101939 = 102000
  • 71 + 101929 = 102000
  • 79 + 101921 = 102000
  • 83 + 101917 = 102000

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 102,000 and was likely granted around 1870.

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