Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999950, here are decompositions:

  • 19 + 999931 = 999950
  • 43 + 999907 = 999950
  • 67 + 999883 = 999950
  • 97 + 999853 = 999950
  • 181 + 999769 = 999950
  • 223 + 999727 = 999950
  • 229 + 999721 = 999950
  • 283 + 999667 = 999950

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 999,950 and was likely granted around 1911.

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