Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939540, here are decompositions:

  • 29 + 939511 = 939540
  • 53 + 939487 = 939540
  • 71 + 939469 = 939540
  • 89 + 939451 = 939540
  • 97 + 939443 = 939540
  • 101 + 939439 = 939540
  • 109 + 939431 = 939540
  • 127 + 939413 = 939540

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 939,540 and was likely granted around 1909.

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