Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680000, here are decompositions:

  • 29 + 8679971 = 8680000
  • 47 + 8679953 = 8680000
  • 101 + 8679899 = 8680000
  • 113 + 8679887 = 8680000
  • 233 + 8679767 = 8680000
  • 257 + 8679743 = 8680000
  • 359 + 8679641 = 8680000
  • 383 + 8679617 = 8680000

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 8,680,000 and was likely granted around 2014.

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