Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158206, here are decompositions:

  • 5 + 158201 = 158206
  • 17 + 158189 = 158206
  • 197 + 158009 = 158206
  • 317 + 157889 = 158206
  • 383 + 157823 = 158206
  • 467 + 157739 = 158206
  • 557 + 157649 = 158206
  • 569 + 157637 = 158206

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 158,206 and was likely granted around 1873.

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