Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172936, here are decompositions:

  • 3 + 172933 = 172936
  • 53 + 172883 = 172936
  • 59 + 172877 = 172936
  • 83 + 172853 = 172936
  • 107 + 172829 = 172936
  • 149 + 172787 = 172936
  • 227 + 172709 = 172936
  • 263 + 172673 = 172936

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 172,936 and was likely granted around 1874.

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