Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002818, here are decompositions:

  • 31 + 1002787 = 1002818
  • 67 + 1002751 = 1002818
  • 79 + 1002739 = 1002818
  • 97 + 1002721 = 1002818
  • 109 + 1002709 = 1002818
  • 139 + 1002679 = 1002818
  • 199 + 1002619 = 1002818
  • 241 + 1002577 = 1002818

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 1,002,818 and was likely granted around 1911.

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