Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671490, here are decompositions:

  • 19 + 8671471 = 8671490
  • 43 + 8671447 = 8671490
  • 97 + 8671393 = 8671490
  • 109 + 8671381 = 8671490
  • 127 + 8671363 = 8671490
  • 151 + 8671339 = 8671490
  • 199 + 8671291 = 8671490
  • 241 + 8671249 = 8671490

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 8,671,490 and was likely granted around 2014.

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