Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101786, here are decompositions:

  • 37 + 101749 = 101786
  • 67 + 101719 = 101786
  • 283 + 101503 = 101786
  • 337 + 101449 = 101786
  • 367 + 101419 = 101786
  • 409 + 101377 = 101786
  • 439 + 101347 = 101786
  • 463 + 101323 = 101786

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 101,786 and was likely granted around 1870.

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