Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001240, here are decompositions:

  • 3 + 1001237 = 1001240
  • 43 + 1001197 = 1001240
  • 67 + 1001173 = 1001240
  • 151 + 1001089 = 1001240
  • 199 + 1001041 = 1001240
  • 223 + 1001017 = 1001240
  • 241 + 1000999 = 1001240
  • 271 + 1000969 = 1001240

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 1,001,240 and was likely granted around 1911.

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