Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001218, here are decompositions:

  • 41 + 1001177 = 1001218
  • 59 + 1001159 = 1001218
  • 131 + 1001087 = 1001218
  • 137 + 1001081 = 1001218
  • 149 + 1001069 = 1001218
  • 191 + 1001027 = 1001218
  • 311 + 1000907 = 1001218
  • 359 + 1000859 = 1001218

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 1,001,218 and was likely granted around 1911.

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