Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655600, here are decompositions:

  • 73 + 8655527 = 8655600
  • 103 + 8655497 = 8655600
  • 167 + 8655433 = 8655600
  • 179 + 8655421 = 8655600
  • 197 + 8655403 = 8655600
  • 199 + 8655401 = 8655600
  • 229 + 8655371 = 8655600
  • 251 + 8655349 = 8655600

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 8,655,600 and was likely granted around 2014.

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