Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005478, here are decompositions:

  • 11 + 1005467 = 1005478
  • 41 + 1005437 = 1005478
  • 107 + 1005371 = 1005478
  • 191 + 1005287 = 1005478
  • 239 + 1005239 = 1005478
  • 269 + 1005209 = 1005478
  • 317 + 1005161 = 1005478
  • 347 + 1005131 = 1005478

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 1,005,478 and was likely granted around 1911.

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