Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187464, here are decompositions:

  • 23 + 187441 = 187464
  • 31 + 187433 = 187464
  • 41 + 187423 = 187464
  • 47 + 187417 = 187464
  • 71 + 187393 = 187464
  • 97 + 187367 = 187464
  • 103 + 187361 = 187464
  • 127 + 187337 = 187464

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 187,464 and was likely granted around 1875.

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