Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670420, here are decompositions:

  • 13 + 8670407 = 8670420
  • 23 + 8670397 = 8670420
  • 47 + 8670373 = 8670420
  • 67 + 8670353 = 8670420
  • 89 + 8670331 = 8670420
  • 107 + 8670313 = 8670420
  • 139 + 8670281 = 8670420
  • 163 + 8670257 = 8670420

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 8,670,420 and was likely granted around 2014.

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