Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100900, here are decompositions:
- 47 + 100853 = 100900
- 53 + 100847 = 100900
- 71 + 100829 = 100900
- 89 + 100811 = 100900
- 101 + 100799 = 100900
- 113 + 100787 = 100900
- 131 + 100769 = 100900
- 167 + 100733 = 100900
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 100,900 and was likely granted around 1870.
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.
