Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000490, here are decompositions:

  • 37 + 1000453 = 1000490
  • 61 + 1000429 = 1000490
  • 67 + 1000423 = 1000490
  • 97 + 1000393 = 1000490
  • 109 + 1000381 = 1000490
  • 157 + 1000333 = 1000490
  • 199 + 1000291 = 1000490
  • 241 + 1000249 = 1000490

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 1,000,490 and was likely granted around 1911.

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