Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187726, here are decompositions:

  • 5 + 187721 = 187726
  • 89 + 187637 = 187726
  • 167 + 187559 = 187726
  • 179 + 187547 = 187726
  • 257 + 187469 = 187726
  • 263 + 187463 = 187726
  • 293 + 187433 = 187726
  • 317 + 187409 = 187726

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 187,726 and was likely granted around 1875.

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