Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985900, here are decompositions:

  • 23 + 985877 = 985900
  • 29 + 985871 = 985900
  • 101 + 985799 = 985900
  • 191 + 985709 = 985900
  • 197 + 985703 = 985900
  • 233 + 985667 = 985900
  • 269 + 985631 = 985900
  • 353 + 985547 = 985900

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 985,900 and was likely granted around 1910.

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