Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687190, here are decompositions:

  • 7 + 8687183 = 8687190
  • 19 + 8687171 = 8687190
  • 41 + 8687149 = 8687190
  • 59 + 8687131 = 8687190
  • 73 + 8687117 = 8687190
  • 97 + 8687093 = 8687190
  • 101 + 8687089 = 8687190
  • 103 + 8687087 = 8687190

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 8,687,190 and was likely granted around 2014.

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