Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000690, here are decompositions:

  • 11 + 1000679 = 1000690
  • 23 + 1000667 = 1000690
  • 71 + 1000619 = 1000690
  • 101 + 1000589 = 1000690
  • 113 + 1000577 = 1000690
  • 149 + 1000541 = 1000690
  • 233 + 1000457 = 1000690
  • 263 + 1000427 = 1000690

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 1,000,690 and was likely granted around 1911.

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