Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006866, here are decompositions:

  • 5 + 1006861 = 1006866
  • 13 + 1006853 = 1006866
  • 19 + 1006847 = 1006866
  • 67 + 1006799 = 1006866
  • 83 + 1006783 = 1006866
  • 97 + 1006769 = 1006866
  • 127 + 1006739 = 1006866
  • 229 + 1006637 = 1006866

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 1,006,866 and was likely granted around 1911.

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