Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719120, here are decompositions:

  • 71 + 8719049 = 8719120
  • 83 + 8719037 = 8719120
  • 89 + 8719031 = 8719120
  • 167 + 8718953 = 8719120
  • 233 + 8718887 = 8719120
  • 239 + 8718881 = 8719120
  • 251 + 8718869 = 8719120
  • 269 + 8718851 = 8719120

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 8,719,120 and was likely granted around 2014.

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