Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491760, here are decompositions:

  • 13 + 491747 = 491760
  • 23 + 491737 = 491760
  • 29 + 491731 = 491760
  • 41 + 491719 = 491760
  • 53 + 491707 = 491760
  • 83 + 491677 = 491760
  • 107 + 491653 = 491760
  • 109 + 491651 = 491760

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 491,760 and was likely granted around 1893.

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