Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999970, here are decompositions:

  • 11 + 999959 = 999970
  • 17 + 999953 = 999970
  • 53 + 999917 = 999970
  • 107 + 999863 = 999970
  • 197 + 999773 = 999970
  • 317 + 999653 = 999970
  • 347 + 999623 = 999970
  • 359 + 999611 = 999970

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 999,970 and was likely granted around 1911.

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