Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166712, here are decompositions:

  • 19 + 166693 = 166712
  • 43 + 166669 = 166712
  • 103 + 166609 = 166712
  • 109 + 166603 = 166712
  • 151 + 166561 = 166712
  • 241 + 166471 = 166712
  • 283 + 166429 = 166712
  • 313 + 166399 = 166712

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 166,712 and was likely granted around 1874.

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