Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006490, here are decompositions:

  • 19 + 1006471 = 1006490
  • 97 + 1006393 = 1006490
  • 139 + 1006351 = 1006490
  • 151 + 1006339 = 1006490
  • 157 + 1006333 = 1006490
  • 181 + 1006309 = 1006490
  • 211 + 1006279 = 1006490
  • 223 + 1006267 = 1006490

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 1,006,490 and was likely granted around 1911.

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