Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001178, here are decompositions:

  • 5 + 1001173 = 1001178
  • 19 + 1001159 = 1001178
  • 71 + 1001107 = 1001178
  • 89 + 1001089 = 1001178
  • 97 + 1001081 = 1001178
  • 109 + 1001069 = 1001178
  • 137 + 1001041 = 1001178
  • 151 + 1001027 = 1001178

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 1,001,178 and was likely granted around 1911.

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