Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556506, here are decompositions:

  • 19 + 556487 = 556506
  • 23 + 556483 = 556506
  • 29 + 556477 = 556506
  • 47 + 556459 = 556506
  • 103 + 556403 = 556506
  • 107 + 556399 = 556506
  • 163 + 556343 = 556506
  • 179 + 556327 = 556506

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 556,506 and was likely granted around 1895.

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