Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487600, here are decompositions:

  • 11 + 487589 = 487600
  • 131 + 487469 = 487600
  • 137 + 487463 = 487600
  • 173 + 487427 = 487600
  • 251 + 487349 = 487600
  • 293 + 487307 = 487600
  • 317 + 487283 = 487600
  • 353 + 487247 = 487600

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 487,600 and was likely granted around 1892.

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