Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001942, here are decompositions:

  • 31 + 1001911 = 1001942
  • 103 + 1001839 = 1001942
  • 199 + 1001743 = 1001942
  • 229 + 1001713 = 1001942
  • 283 + 1001659 = 1001942
  • 313 + 1001629 = 1001942
  • 349 + 1001593 = 1001942
  • 373 + 1001569 = 1001942

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 1,001,942 and was likely granted around 1911.

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