Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512724, here are decompositions:
- 7 + 512717 = 512724
- 11 + 512713 = 512724
- 13 + 512711 = 512724
- 41 + 512683 = 512724
- 53 + 512671 = 512724
- 61 + 512663 = 512724
- 67 + 512657 = 512724
- 83 + 512641 = 512724
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 512,724 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
