Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188782, here are decompositions:

  • 3 + 188779 = 188782
  • 29 + 188753 = 188782
  • 53 + 188729 = 188782
  • 71 + 188711 = 188782
  • 89 + 188693 = 188782
  • 101 + 188681 = 188782
  • 149 + 188633 = 188782
  • 173 + 188609 = 188782

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 188,782 and was likely granted around 1875.

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