Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189984, here are decompositions:

  • 7 + 189977 = 189984
  • 17 + 189967 = 189984
  • 23 + 189961 = 189984
  • 37 + 189947 = 189984
  • 71 + 189913 = 189984
  • 83 + 189901 = 189984
  • 97 + 189887 = 189984
  • 103 + 189881 = 189984

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 189,984 and was likely granted around 1875.

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