Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670784, here are decompositions:

  • 11 + 8670773 = 8670784
  • 41 + 8670743 = 8670784
  • 71 + 8670713 = 8670784
  • 131 + 8670653 = 8670784
  • 173 + 8670611 = 8670784
  • 233 + 8670551 = 8670784
  • 251 + 8670533 = 8670784
  • 281 + 8670503 = 8670784

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 8,670,784 and was likely granted around 2014.

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