Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491364, here are decompositions:

  • 7 + 491357 = 491364
  • 11 + 491353 = 491364
  • 23 + 491341 = 491364
  • 31 + 491333 = 491364
  • 37 + 491327 = 491364
  • 67 + 491297 = 491364
  • 103 + 491261 = 491364
  • 113 + 491251 = 491364

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 491,364 and was likely granted around 1893.

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