Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680540, here are decompositions:

  • 59 + 8680481 = 8680540
  • 101 + 8680439 = 8680540
  • 131 + 8680409 = 8680540
  • 149 + 8680391 = 8680540
  • 227 + 8680313 = 8680540
  • 233 + 8680307 = 8680540
  • 263 + 8680277 = 8680540
  • 311 + 8680229 = 8680540

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 8,680,540 and was likely granted around 2014.

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