Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668740, here are decompositions:

  • 19 + 8668721 = 8668740
  • 29 + 8668711 = 8668740
  • 43 + 8668697 = 8668740
  • 53 + 8668687 = 8668740
  • 97 + 8668643 = 8668740
  • 103 + 8668637 = 8668740
  • 127 + 8668613 = 8668740
  • 131 + 8668609 = 8668740

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 8,668,740 and was likely granted around 2014.

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