Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510720, here are decompositions:
- 11 + 510709 = 510720
- 13 + 510707 = 510720
- 29 + 510691 = 510720
- 37 + 510683 = 510720
- 43 + 510677 = 510720
- 101 + 510619 = 510720
- 103 + 510617 = 510720
- 107 + 510613 = 510720
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 510,720 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
