Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005644, here are decompositions:

  • 7 + 1005637 = 1005644
  • 103 + 1005541 = 1005644
  • 151 + 1005493 = 1005644
  • 163 + 1005481 = 1005644
  • 271 + 1005373 = 1005644
  • 313 + 1005331 = 1005644
  • 331 + 1005313 = 1005644
  • 421 + 1005223 = 1005644

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 1,005,644 and was likely granted around 1911.

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