Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677820, here are decompositions:

  • 61 + 8677759 = 8677820
  • 97 + 8677723 = 8677820
  • 139 + 8677681 = 8677820
  • 157 + 8677663 = 8677820
  • 337 + 8677483 = 8677820
  • 367 + 8677453 = 8677820
  • 421 + 8677399 = 8677820
  • 433 + 8677387 = 8677820

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 8,677,820 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.

Federal Reserve
United States Government

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
