Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189500, here are decompositions:

  • 7 + 189493 = 189500
  • 37 + 189463 = 189500
  • 61 + 189439 = 189500
  • 67 + 189433 = 189500
  • 79 + 189421 = 189500
  • 109 + 189391 = 189500
  • 139 + 189361 = 189500
  • 151 + 189349 = 189500

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 189,500 and was likely granted around 1875.

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