Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005646, here are decompositions:

  • 3 + 1005643 = 1005646
  • 29 + 1005617 = 1005646
  • 53 + 1005593 = 1005646
  • 179 + 1005467 = 1005646
  • 233 + 1005413 = 1005646
  • 353 + 1005293 = 1005646
  • 359 + 1005287 = 1005646
  • 443 + 1005203 = 1005646

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 1,005,646 and was likely granted around 1911.

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