Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551740, here are decompositions:

  • 11 + 551729 = 551740
  • 17 + 551723 = 551740
  • 23 + 551717 = 551740
  • 47 + 551693 = 551740
  • 89 + 551651 = 551740
  • 191 + 551549 = 551740
  • 197 + 551543 = 551740
  • 251 + 551489 = 551740

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 551,740 and was likely granted around 1895.

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