Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178224, here are decompositions:

  • 17 + 178207 = 178224
  • 37 + 178187 = 178224
  • 41 + 178183 = 178224
  • 73 + 178151 = 178224
  • 83 + 178141 = 178224
  • 97 + 178127 = 178224
  • 107 + 178117 = 178224
  • 131 + 178093 = 178224

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 178,224 and was likely granted around 1874.

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