Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101380, here are decompositions:

  • 3 + 101377 = 101380
  • 17 + 101363 = 101380
  • 47 + 101333 = 101380
  • 101 + 101279 = 101380
  • 107 + 101273 = 101380
  • 113 + 101267 = 101380
  • 173 + 101207 = 101380
  • 197 + 101183 = 101380

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 101,380 and was likely granted around 1870.

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