Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515426, here are decompositions:

  • 103 + 515323 = 515426
  • 193 + 515233 = 515426
  • 199 + 515227 = 515426
  • 277 + 515149 = 515426
  • 283 + 515143 = 515426
  • 337 + 515089 = 515426
  • 487 + 514939 = 515426
  • 523 + 514903 = 515426

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 515,426 and was likely granted around 1894.

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