Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166470, here are decompositions:

  • 13 + 166457 = 166470
  • 41 + 166429 = 166470
  • 53 + 166417 = 166470
  • 61 + 166409 = 166470
  • 67 + 166403 = 166470
  • 71 + 166399 = 166470
  • 107 + 166363 = 166470
  • 113 + 166357 = 166470

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 166,470 and was likely granted around 1874.

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