Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555380, here are decompositions:

  • 19 + 555361 = 555380
  • 31 + 555349 = 555380
  • 43 + 555337 = 555380
  • 73 + 555307 = 555380
  • 79 + 555301 = 555380
  • 103 + 555277 = 555380
  • 127 + 555253 = 555380
  • 271 + 555109 = 555380

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 555,380 and was likely granted around 1895.

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