Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513184, here are decompositions:
- 11 + 513173 = 513184
- 17 + 513167 = 513184
- 47 + 513137 = 513184
- 53 + 513131 = 513184
- 83 + 513101 = 513184
- 101 + 513083 = 513184
- 131 + 513053 = 513184
- 137 + 513047 = 513184
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 513,184 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
