Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100408, here are decompositions:

  • 5 + 100403 = 100408
  • 17 + 100391 = 100408
  • 29 + 100379 = 100408
  • 47 + 100361 = 100408
  • 137 + 100271 = 100408
  • 239 + 100169 = 100408
  • 257 + 100151 = 100408
  • 359 + 100049 = 100408

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 100,408 and was likely granted around 1870.

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