Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685242, here are decompositions:

  • 31 + 8685211 = 8685242
  • 43 + 8685199 = 8685242
  • 199 + 8685043 = 8685242
  • 211 + 8685031 = 8685242
  • 229 + 8685013 = 8685242
  • 283 + 8684959 = 8685242
  • 331 + 8684911 = 8685242
  • 421 + 8684821 = 8685242

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 8,685,242 and was likely granted around 2014.

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