Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008880, here are decompositions:

  • 17 + 1008863 = 1008880
  • 23 + 1008857 = 1008880
  • 29 + 1008851 = 1008880
  • 71 + 1008809 = 1008880
  • 101 + 1008779 = 1008880
  • 107 + 1008773 = 1008880
  • 137 + 1008743 = 1008880
  • 179 + 1008701 = 1008880

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 1,008,880 and was likely granted around 1911.

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