Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187958, here are decompositions:

  • 7 + 187951 = 187958
  • 31 + 187927 = 187958
  • 37 + 187921 = 187958
  • 61 + 187897 = 187958
  • 97 + 187861 = 187958
  • 271 + 187687 = 187958
  • 307 + 187651 = 187958
  • 487 + 187471 = 187958

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 187,958 and was likely granted around 1875.

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