Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128410, here are decompositions:

  • 11 + 128399 = 128410
  • 17 + 128393 = 128410
  • 59 + 128351 = 128410
  • 71 + 128339 = 128410
  • 83 + 128327 = 128410
  • 89 + 128321 = 128410
  • 137 + 128273 = 128410
  • 173 + 128237 = 128410

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 128,410 and was likely granted around 1872.

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