Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000538, here are decompositions:

  • 31 + 1000507 = 1000538
  • 109 + 1000429 = 1000538
  • 157 + 1000381 = 1000538
  • 181 + 1000357 = 1000538
  • 307 + 1000231 = 1000538
  • 367 + 1000171 = 1000538
  • 379 + 1000159 = 1000538
  • 421 + 1000117 = 1000538

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 1,000,538 and was likely granted around 1911.

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