Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671838, here are decompositions:

  • 127 + 8671711 = 8671838
  • 199 + 8671639 = 8671838
  • 337 + 8671501 = 8671838
  • 367 + 8671471 = 8671838
  • 397 + 8671441 = 8671838
  • 457 + 8671381 = 8671838
  • 499 + 8671339 = 8671838
  • 547 + 8671291 = 8671838

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 8,671,838 and was likely granted around 2014.

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