Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189112, here are decompositions:

  • 71 + 189041 = 189112
  • 101 + 189011 = 189112
  • 113 + 188999 = 189112
  • 173 + 188939 = 189112
  • 179 + 188933 = 189112
  • 251 + 188861 = 189112
  • 269 + 188843 = 189112
  • 281 + 188831 = 189112

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 189,112 and was likely granted around 1875.

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