Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557840, here are decompositions:

  • 37 + 557803 = 557840
  • 61 + 557779 = 557840
  • 79 + 557761 = 557840
  • 97 + 557743 = 557840
  • 109 + 557731 = 557840
  • 229 + 557611 = 557840
  • 307 + 557533 = 557840
  • 379 + 557461 = 557840

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 557,840 and was likely granted around 1895.

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