Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670540, here are decompositions:

  • 7 + 8670533 = 8670540
  • 17 + 8670523 = 8670540
  • 31 + 8670509 = 8670540
  • 37 + 8670503 = 8670540
  • 41 + 8670499 = 8670540
  • 59 + 8670481 = 8670540
  • 89 + 8670451 = 8670540
  • 107 + 8670433 = 8670540

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 8,670,540 and was likely granted around 2014.

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