Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511328, here are decompositions:

  • 31 + 511297 = 511328
  • 67 + 511261 = 511328
  • 127 + 511201 = 511328
  • 151 + 511177 = 511328
  • 157 + 511171 = 511328
  • 241 + 511087 = 511328
  • 271 + 511057 = 511328
  • 397 + 510931 = 511328

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 511,328 and was likely granted around 1893.

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