Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182020, here are decompositions:

  • 11 + 182009 = 182020
  • 23 + 181997 = 182020
  • 53 + 181967 = 182020
  • 89 + 181931 = 182020
  • 101 + 181919 = 182020
  • 107 + 181913 = 182020
  • 131 + 181889 = 182020
  • 149 + 181871 = 182020

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 182,020 and was likely granted around 1875.

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