Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005186, here are decompositions:

  • 43 + 1005143 = 1005186
  • 53 + 1005133 = 1005186
  • 79 + 1005107 = 1005186
  • 107 + 1005079 = 1005186
  • 113 + 1005073 = 1005186
  • 137 + 1005049 = 1005186
  • 157 + 1005029 = 1005186
  • 167 + 1005019 = 1005186

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 1,005,186 and was likely granted around 1911.

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