Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187108, here are decompositions:

  • 17 + 187091 = 187108
  • 41 + 187067 = 187108
  • 59 + 187049 = 187108
  • 149 + 186959 = 187108
  • 191 + 186917 = 187108
  • 239 + 186869 = 187108
  • 347 + 186761 = 187108
  • 401 + 186707 = 187108

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 187,108 and was likely granted around 1875.

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