Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515436, here are decompositions:

  • 7 + 515429 = 515436
  • 59 + 515377 = 515436
  • 67 + 515369 = 515436
  • 79 + 515357 = 515436
  • 113 + 515323 = 515436
  • 157 + 515279 = 515436
  • 199 + 515237 = 515436
  • 263 + 515173 = 515436

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 515,436 and was likely granted around 1894.

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