Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102208, here are decompositions:

  • 5 + 102203 = 102208
  • 11 + 102197 = 102208
  • 17 + 102191 = 102208
  • 47 + 102161 = 102208
  • 59 + 102149 = 102208
  • 101 + 102107 = 102208
  • 107 + 102101 = 102208
  • 131 + 102077 = 102208

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 102,208 and was likely granted around 1870.

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