Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002866, here are decompositions:

  • 3 + 1002863 = 1002866
  • 13 + 1002853 = 1002866
  • 79 + 1002787 = 1002866
  • 97 + 1002769 = 1002866
  • 127 + 1002739 = 1002866
  • 157 + 1002709 = 1002866
  • 283 + 1002583 = 1002866
  • 313 + 1002553 = 1002866

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 1,002,866 and was likely granted around 1911.

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