Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749000, here are decompositions:

  • 11 + 8748989 = 8749000
  • 47 + 8748953 = 8749000
  • 107 + 8748893 = 8749000
  • 173 + 8748827 = 8749000
  • 179 + 8748821 = 8749000
  • 233 + 8748767 = 8749000
  • 257 + 8748743 = 8749000
  • 269 + 8748731 = 8749000

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 8,749,000 and was likely granted around 2014.

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