Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667538, here are decompositions:

  • 17 + 8667521 = 8667538
  • 41 + 8667497 = 8667538
  • 107 + 8667431 = 8667538
  • 167 + 8667371 = 8667538
  • 239 + 8667299 = 8667538
  • 281 + 8667257 = 8667538
  • 311 + 8667227 = 8667538
  • 359 + 8667179 = 8667538

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 8,667,538 and was likely granted around 2014.

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