Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670440, here are decompositions:

  • 7 + 8670433 = 8670440
  • 43 + 8670397 = 8670440
  • 67 + 8670373 = 8670440
  • 109 + 8670331 = 8670440
  • 127 + 8670313 = 8670440
  • 139 + 8670301 = 8670440
  • 283 + 8670157 = 8670440
  • 313 + 8670127 = 8670440

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 8,670,440 and was likely granted around 2014.

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