Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178706, here are decompositions:

  • 13 + 178693 = 178706
  • 67 + 178639 = 178706
  • 79 + 178627 = 178706
  • 97 + 178609 = 178706
  • 103 + 178603 = 178706
  • 109 + 178597 = 178706
  • 139 + 178567 = 178706
  • 193 + 178513 = 178706

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 178,706 and was likely granted around 1875.

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