Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521272, here are decompositions:

  • 5 + 521267 = 521272
  • 29 + 521243 = 521272
  • 41 + 521231 = 521272
  • 71 + 521201 = 521272
  • 233 + 521039 = 521272
  • 251 + 521021 = 521272
  • 263 + 521009 = 521272
  • 359 + 520913 = 521272

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 521,272 and was likely granted around 1894.

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