Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100378, here are decompositions:

  • 17 + 100361 = 100378
  • 107 + 100271 = 100378
  • 227 + 100151 = 100378
  • 269 + 100109 = 100378
  • 359 + 100019 = 100378
  • 389 + 99989 = 100378
  • 449 + 99929 = 100378
  • 569 + 99809 = 100378

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 100,378 and was likely granted around 1870.

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