Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678340, here are decompositions:

  • 7 + 8678333 = 8678340
  • 17 + 8678323 = 8678340
  • 29 + 8678311 = 8678340
  • 103 + 8678237 = 8678340
  • 127 + 8678213 = 8678340
  • 137 + 8678203 = 8678340
  • 179 + 8678161 = 8678340
  • 191 + 8678149 = 8678340

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 8,678,340 and was likely granted around 2014.

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

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
