Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490816, here are decompositions:

  • 47 + 490769 = 490816
  • 83 + 490733 = 490816
  • 173 + 490643 = 490816
  • 197 + 490619 = 490816
  • 239 + 490577 = 490816
  • 257 + 490559 = 490816
  • 317 + 490499 = 490816
  • 353 + 490463 = 490816

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 490,816 and was likely granted around 1892.

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