Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005018, here are decompositions:

  • 5 + 1005013 = 1005018
  • 11 + 1005007 = 1005018
  • 31 + 1004987 = 1005018
  • 37 + 1004981 = 1005018
  • 41 + 1004977 = 1005018
  • 101 + 1004917 = 1005018
  • 107 + 1004911 = 1005018
  • 239 + 1004779 = 1005018

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 1,005,018 and was likely granted around 1911.

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