Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490656, here are decompositions:

  • 13 + 490643 = 490656
  • 29 + 490627 = 490656
  • 37 + 490619 = 490656
  • 79 + 490577 = 490656
  • 83 + 490573 = 490656
  • 97 + 490559 = 490656
  • 107 + 490549 = 490656
  • 113 + 490543 = 490656

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 490,656 and was likely granted around 1892.

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