Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001390, here are decompositions:

  • 3 + 1001387 = 1001390
  • 37 + 1001353 = 1001390
  • 43 + 1001347 = 1001390
  • 67 + 1001323 = 1001390
  • 79 + 1001311 = 1001390
  • 193 + 1001197 = 1001390
  • 199 + 1001191 = 1001390
  • 283 + 1001107 = 1001390

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 1,001,390 and was likely granted around 1911.

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