Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491494, here are decompositions:

  • 5 + 491489 = 491494
  • 11 + 491483 = 491494
  • 71 + 491423 = 491494
  • 137 + 491357 = 491494
  • 167 + 491327 = 491494
  • 197 + 491297 = 491494
  • 233 + 491261 = 491494
  • 281 + 491213 = 491494

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 491,494 and was likely granted around 1893.

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