Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516538, here are decompositions:

  • 17 + 516521 = 516538
  • 89 + 516449 = 516538
  • 101 + 516437 = 516538
  • 107 + 516431 = 516538
  • 131 + 516407 = 516538
  • 167 + 516371 = 516538
  • 179 + 516359 = 516538
  • 311 + 516227 = 516538

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 516,538 and was likely granted around 1894.

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