Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676840, here are decompositions:

  • 13 + 8676827 = 8676840
  • 19 + 8676821 = 8676840
  • 41 + 8676799 = 8676840
  • 59 + 8676781 = 8676840
  • 61 + 8676779 = 8676840
  • 71 + 8676769 = 8676840
  • 83 + 8676757 = 8676840
  • 89 + 8676751 = 8676840

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 8,676,840 and was likely granted around 2014.

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