Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679520, here are decompositions:

  • 71 + 8679449 = 8679520
  • 167 + 8679353 = 8679520
  • 173 + 8679347 = 8679520
  • 383 + 8679137 = 8679520
  • 449 + 8679071 = 8679520
  • 461 + 8679059 = 8679520
  • 557 + 8678963 = 8679520
  • 569 + 8678951 = 8679520

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 8,679,520 and was likely granted around 2014.

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