Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513120, here are decompositions:
- 11 + 513109 = 513120
- 17 + 513103 = 513120
- 19 + 513101 = 513120
- 37 + 513083 = 513120
- 53 + 513067 = 513120
- 61 + 513059 = 513120
- 67 + 513053 = 513120
- 73 + 513047 = 513120
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 513,120 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
