Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663180, here are decompositions:

  • 61 + 8663119 = 8663180
  • 79 + 8663101 = 8663180
  • 109 + 8663071 = 8663180
  • 157 + 8663023 = 8663180
  • 193 + 8662987 = 8663180
  • 241 + 8662939 = 8663180
  • 313 + 8662867 = 8663180
  • 349 + 8662831 = 8663180

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 8,663,180 and was likely granted around 2014.

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