Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513248, here are decompositions:
- 79 + 513169 = 513248
- 139 + 513109 = 513248
- 181 + 513067 = 513248
- 271 + 512977 = 513248
- 331 + 512917 = 513248
- 349 + 512899 = 513248
- 487 + 512761 = 513248
- 577 + 512671 = 513248
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 513,248 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
