Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691500, here are decompositions:

  • 3 + 8691497 = 8691500
  • 19 + 8691481 = 8691500
  • 31 + 8691469 = 8691500
  • 67 + 8691433 = 8691500
  • 109 + 8691391 = 8691500
  • 127 + 8691373 = 8691500
  • 271 + 8691229 = 8691500
  • 277 + 8691223 = 8691500

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 8,691,500 and was likely granted around 2014.

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