Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126168, here are decompositions:

  • 17 + 126151 = 126168
  • 37 + 126131 = 126168
  • 41 + 126127 = 126168
  • 61 + 126107 = 126168
  • 71 + 126097 = 126168
  • 89 + 126079 = 126168
  • 101 + 126067 = 126168
  • 127 + 126041 = 126168

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 126,168 and was likely granted around 1872.

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