Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171850, here are decompositions:

  • 23 + 171827 = 171850
  • 47 + 171803 = 171850
  • 89 + 171761 = 171850
  • 131 + 171719 = 171850
  • 137 + 171713 = 171850
  • 179 + 171671 = 171850
  • 191 + 171659 = 171850
  • 197 + 171653 = 171850

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 171,850 and was likely granted around 1874.

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