Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525580, here are decompositions:

  • 47 + 525533 = 525580
  • 89 + 525491 = 525580
  • 113 + 525467 = 525580
  • 149 + 525431 = 525580
  • 227 + 525353 = 525580
  • 281 + 525299 = 525580
  • 359 + 525221 = 525580
  • 389 + 525191 = 525580

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 525,580 and was likely granted around 1894.

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