Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481540, here are decompositions:

  • 71 + 481469 = 481540
  • 107 + 481433 = 481540
  • 131 + 481409 = 481540
  • 167 + 481373 = 481540
  • 197 + 481343 = 481540
  • 233 + 481307 = 481540
  • 239 + 481301 = 481540
  • 359 + 481181 = 481540

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 481,540 and was likely granted around 1892.

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