Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511264, here are decompositions:

  • 3 + 511261 = 511264
  • 41 + 511223 = 511264
  • 53 + 511211 = 511264
  • 71 + 511193 = 511264
  • 101 + 511163 = 511264
  • 113 + 511151 = 511264
  • 251 + 511013 = 511264
  • 263 + 511001 = 511264

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 511,264 and was likely granted around 1893.

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