Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513162, here are decompositions:
- 5 + 513157 = 513162
- 31 + 513131 = 513162
- 53 + 513109 = 513162
- 59 + 513103 = 513162
- 61 + 513101 = 513162
- 79 + 513083 = 513162
- 103 + 513059 = 513162
- 109 + 513053 = 513162
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 513,162 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
