Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512500, here are decompositions:

  • 3 + 512497 = 512500
  • 71 + 512429 = 512500
  • 167 + 512333 = 512500
  • 179 + 512321 = 512500
  • 251 + 512249 = 512500
  • 293 + 512207 = 512500
  • 353 + 512147 = 512500
  • 479 + 512021 = 512500

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 512,500 and was likely granted around 1893.

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