Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513170, here are decompositions:
- 3 + 513167 = 513170
- 13 + 513157 = 513170
- 61 + 513109 = 513170
- 67 + 513103 = 513170
- 103 + 513067 = 513170
- 139 + 513031 = 513170
- 157 + 513013 = 513170
- 181 + 512989 = 513170
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 513,170 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
