Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180824, here are decompositions:

  • 13 + 180811 = 180824
  • 31 + 180793 = 180824
  • 73 + 180751 = 180824
  • 157 + 180667 = 180824
  • 277 + 180547 = 180824
  • 283 + 180541 = 180824
  • 313 + 180511 = 180824
  • 433 + 180391 = 180824

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 180,824 and was likely granted around 1875.

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