Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102168, here are decompositions:

  • 7 + 102161 = 102168
  • 19 + 102149 = 102168
  • 29 + 102139 = 102168
  • 47 + 102121 = 102168
  • 61 + 102107 = 102168
  • 67 + 102101 = 102168
  • 89 + 102079 = 102168
  • 97 + 102071 = 102168

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 102,168 and was likely granted around 1870.

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