Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671402, here are decompositions:
- 41 + 8671361 = 8671402
- 71 + 8671331 = 8671402
- 251 + 8671151 = 8671402
- 269 + 8671133 = 8671402
- 461 + 8670941 = 8671402
- 659 + 8670743 = 8671402
- 911 + 8670491 = 8671402
- 1031 + 8670371 = 8671402
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,671,402 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
