Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680040, here are decompositions:

  • 3 + 8680037 = 8680040
  • 7 + 8680033 = 8680040
  • 13 + 8680027 = 8680040
  • 37 + 8680003 = 8680040
  • 67 + 8679973 = 8680040
  • 97 + 8679943 = 8680040
  • 157 + 8679883 = 8680040
  • 199 + 8679841 = 8680040

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 8,680,040 and was likely granted around 2014.

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