Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125684, here are decompositions:

  • 43 + 125641 = 125684
  • 67 + 125617 = 125684
  • 157 + 125527 = 125684
  • 277 + 125407 = 125684
  • 313 + 125371 = 125684
  • 331 + 125353 = 125684
  • 373 + 125311 = 125684
  • 397 + 125287 = 125684

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 125,684 and was likely granted around 1871.

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