Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528580, here are decompositions:

  • 53 + 528527 = 528580
  • 71 + 528509 = 528580
  • 89 + 528491 = 528580
  • 167 + 528413 = 528580
  • 179 + 528401 = 528580
  • 197 + 528383 = 528580
  • 251 + 528329 = 528580
  • 263 + 528317 = 528580

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 528,580 and was likely granted around 1894.

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