Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163256, here are decompositions:

  • 7 + 163249 = 163256
  • 13 + 163243 = 163256
  • 109 + 163147 = 163256
  • 127 + 163129 = 163256
  • 139 + 163117 = 163256
  • 193 + 163063 = 163256
  • 229 + 163027 = 163256
  • 283 + 162973 = 163256

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 163,256 and was likely granted around 1874.

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