Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000646, here are decompositions:

  • 7 + 1000639 = 1000646
  • 37 + 1000609 = 1000646
  • 67 + 1000579 = 1000646
  • 109 + 1000537 = 1000646
  • 139 + 1000507 = 1000646
  • 193 + 1000453 = 1000646
  • 223 + 1000423 = 1000646
  • 313 + 1000333 = 1000646

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 1,000,646 and was likely granted around 1911.

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