Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601890, here are decompositions:

  • 7 + 8601883 = 8601890
  • 13 + 8601877 = 8601890
  • 67 + 8601823 = 8601890
  • 151 + 8601739 = 8601890
  • 163 + 8601727 = 8601890
  • 223 + 8601667 = 8601890
  • 379 + 8601511 = 8601890
  • 433 + 8601457 = 8601890

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 8,601,890 and was likely granted around 2013.

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