Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125732, here are decompositions:

  • 73 + 125659 = 125732
  • 181 + 125551 = 125732
  • 193 + 125539 = 125732
  • 223 + 125509 = 125732
  • 349 + 125383 = 125732
  • 379 + 125353 = 125732
  • 421 + 125311 = 125732
  • 433 + 125299 = 125732

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 125,732 and was likely granted around 1871.

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