Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180456, here are decompositions:

  • 19 + 180437 = 180456
  • 37 + 180419 = 180456
  • 43 + 180413 = 180456
  • 109 + 180347 = 180456
  • 139 + 180317 = 180456
  • 149 + 180307 = 180456
  • 167 + 180289 = 180456
  • 193 + 180263 = 180456

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 180,456 and was likely granted around 1875.

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