Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551938, here are decompositions:

  • 5 + 551933 = 551938
  • 11 + 551927 = 551938
  • 29 + 551909 = 551938
  • 89 + 551849 = 551938
  • 137 + 551801 = 551938
  • 389 + 551549 = 551938
  • 419 + 551519 = 551938
  • 449 + 551489 = 551938

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 551,938 and was likely granted around 1895.

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