Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615500, here are decompositions:

  • 29 + 8615471 = 8615500
  • 167 + 8615333 = 8615500
  • 227 + 8615273 = 8615500
  • 233 + 8615267 = 8615500
  • 239 + 8615261 = 8615500
  • 263 + 8615237 = 8615500
  • 269 + 8615231 = 8615500
  • 281 + 8615219 = 8615500

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 8,615,500 and was likely granted around 2013.

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