Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513402, here are decompositions:
- 5 + 513397 = 513402
- 31 + 513371 = 513402
- 61 + 513341 = 513402
- 83 + 513319 = 513402
- 89 + 513313 = 513402
- 163 + 513239 = 513402
- 199 + 513203 = 513402
- 229 + 513173 = 513402
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 513,402 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
