Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005900, here are decompositions:

  • 17 + 1005883 = 1005900
  • 67 + 1005833 = 1005900
  • 73 + 1005827 = 1005900
  • 79 + 1005821 = 1005900
  • 139 + 1005761 = 1005900
  • 149 + 1005751 = 1005900
  • 191 + 1005709 = 1005900
  • 199 + 1005701 = 1005900

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 1,005,900 and was likely granted around 1911.

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