Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008666, here are decompositions:

  • 7 + 1008659 = 1008666
  • 53 + 1008613 = 1008666
  • 59 + 1008607 = 1008666
  • 79 + 1008587 = 1008666
  • 103 + 1008563 = 1008666
  • 149 + 1008517 = 1008666
  • 163 + 1008503 = 1008666
  • 167 + 1008499 = 1008666

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 1,008,666 and was likely granted around 1911.

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