Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005912, here are decompositions:

  • 29 + 1005883 = 1005912
  • 79 + 1005833 = 1005912
  • 151 + 1005761 = 1005912
  • 211 + 1005701 = 1005912
  • 233 + 1005679 = 1005912
  • 251 + 1005661 = 1005912
  • 269 + 1005643 = 1005912
  • 293 + 1005619 = 1005912

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 1,005,912 and was likely granted around 1911.

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