Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002280, here are decompositions:

  • 17 + 1002263 = 1002280
  • 23 + 1002257 = 1002280
  • 53 + 1002227 = 1002280
  • 89 + 1002191 = 1002280
  • 107 + 1002173 = 1002280
  • 131 + 1002149 = 1002280
  • 137 + 1002143 = 1002280
  • 179 + 1002101 = 1002280

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 1,002,280 and was likely granted around 1911.

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