Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670990, here are decompositions:

  • 43 + 8670947 = 8670990
  • 47 + 8670943 = 8670990
  • 71 + 8670919 = 8670990
  • 103 + 8670887 = 8670990
  • 127 + 8670863 = 8670990
  • 179 + 8670811 = 8670990
  • 199 + 8670791 = 8670990
  • 239 + 8670751 = 8670990

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 8,670,990 and was likely granted around 2014.

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