Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171958, here are decompositions:

  • 11 + 171947 = 171958
  • 29 + 171929 = 171958
  • 41 + 171917 = 171958
  • 89 + 171869 = 171958
  • 107 + 171851 = 171958
  • 131 + 171827 = 171958
  • 197 + 171761 = 171958
  • 239 + 171719 = 171958

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 171,958 and was likely granted around 1874.

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