Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000280, here are decompositions:

  • 7 + 1000273 = 1000280
  • 31 + 1000249 = 1000280
  • 67 + 1000213 = 1000280
  • 97 + 1000183 = 1000280
  • 109 + 1000171 = 1000280
  • 163 + 1000117 = 1000280
  • 181 + 1000099 = 1000280
  • 199 + 1000081 = 1000280

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 1,000,280 and was likely granted around 1911.

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