Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005650, here are decompositions:

  • 3 + 1005647 = 1005650
  • 7 + 1005643 = 1005650
  • 13 + 1005637 = 1005650
  • 31 + 1005619 = 1005650
  • 97 + 1005553 = 1005650
  • 109 + 1005541 = 1005650
  • 157 + 1005493 = 1005650
  • 193 + 1005457 = 1005650

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 1,005,650 and was likely granted around 1911.

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