Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002784, here are decompositions:

  • 11 + 1002773 = 1002784
  • 17 + 1002767 = 1002784
  • 71 + 1002713 = 1002784
  • 131 + 1002653 = 1002784
  • 137 + 1002647 = 1002784
  • 257 + 1002527 = 1002784
  • 281 + 1002503 = 1002784
  • 317 + 1002467 = 1002784

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 1,002,784 and was likely granted around 1911.

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