Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678400, here are decompositions:

  • 7 + 8678393 = 8678400
  • 37 + 8678363 = 8678400
  • 41 + 8678359 = 8678400
  • 47 + 8678353 = 8678400
  • 61 + 8678339 = 8678400
  • 67 + 8678333 = 8678400
  • 89 + 8678311 = 8678400
  • 163 + 8678237 = 8678400

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 8,678,400 and was likely granted around 2014.

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