Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000636, here are decompositions:

  • 17 + 1000619 = 1000636
  • 47 + 1000589 = 1000636
  • 59 + 1000577 = 1000636
  • 89 + 1000547 = 1000636
  • 179 + 1000457 = 1000636
  • 227 + 1000409 = 1000636
  • 233 + 1000403 = 1000636
  • 239 + 1000397 = 1000636

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 1,000,636 and was likely granted around 1911.

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