Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678538, here are decompositions:

  • 19 + 8678519 = 8678538
  • 31 + 8678507 = 8678538
  • 139 + 8678399 = 8678538
  • 179 + 8678359 = 8678538
  • 199 + 8678339 = 8678538
  • 227 + 8678311 = 8678538
  • 359 + 8678179 = 8678538
  • 389 + 8678149 = 8678538

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 8,678,538 and was likely granted around 2014.

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