Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187964, here are decompositions:

  • 13 + 187951 = 187964
  • 37 + 187927 = 187964
  • 43 + 187921 = 187964
  • 67 + 187897 = 187964
  • 103 + 187861 = 187964
  • 277 + 187687 = 187964
  • 313 + 187651 = 187964
  • 331 + 187633 = 187964

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 187,964 and was likely granted around 1875.

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