Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556540, here are decompositions:

  • 3 + 556537 = 556540
  • 53 + 556487 = 556540
  • 137 + 556403 = 556540
  • 167 + 556373 = 556540
  • 197 + 556343 = 556540
  • 227 + 556313 = 556540
  • 251 + 556289 = 556540
  • 269 + 556271 = 556540

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 556,540 and was likely granted around 1895.

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