Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669844, here are decompositions:

  • 13 + 8669831 = 8669844
  • 23 + 8669821 = 8669844
  • 67 + 8669777 = 8669844
  • 173 + 8669671 = 8669844
  • 193 + 8669651 = 8669844
  • 223 + 8669621 = 8669844
  • 233 + 8669611 = 8669844
  • 251 + 8669593 = 8669844

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 8,669,844 and was likely granted around 2014.

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