Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008580, here are decompositions:

  • 17 + 1008563 = 1008580
  • 113 + 1008467 = 1008580
  • 173 + 1008407 = 1008580
  • 179 + 1008401 = 1008580
  • 227 + 1008353 = 1008580
  • 233 + 1008347 = 1008580
  • 257 + 1008323 = 1008580
  • 263 + 1008317 = 1008580

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 1,008,580 and was likely granted around 1911.

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