Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005860, here are decompositions:

  • 109 + 1005751 = 1005860
  • 151 + 1005709 = 1005860
  • 181 + 1005679 = 1005860
  • 199 + 1005661 = 1005860
  • 223 + 1005637 = 1005860
  • 241 + 1005619 = 1005860
  • 307 + 1005553 = 1005860
  • 367 + 1005493 = 1005860

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 1,005,860 and was likely granted around 1911.

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