Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678172, here are decompositions:

  • 11 + 8678161 = 8678172
  • 23 + 8678149 = 8678172
  • 31 + 8678141 = 8678172
  • 43 + 8678129 = 8678172
  • 59 + 8678113 = 8678172
  • 79 + 8678093 = 8678172
  • 89 + 8678083 = 8678172
  • 103 + 8678069 = 8678172

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 8,678,172 and was likely granted around 2014.

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