Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509724, here are decompositions:
- 31 + 509693 = 509724
- 37 + 509687 = 509724
- 43 + 509681 = 509724
- 71 + 509653 = 509724
- 101 + 509623 = 509724
- 151 + 509573 = 509724
- 167 + 509557 = 509724
- 181 + 509543 = 509724
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 509,724 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
