Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190208, here are decompositions:

  • 61 + 190147 = 190208
  • 79 + 190129 = 190208
  • 157 + 190051 = 190208
  • 181 + 190027 = 190208
  • 211 + 189997 = 190208
  • 241 + 189967 = 190208
  • 307 + 189901 = 190208
  • 331 + 189877 = 190208

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 190,208 and was likely granted around 1875.

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