Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102562, here are decompositions:
- 3 + 102559 = 102562
- 11 + 102551 = 102562
- 23 + 102539 = 102562
- 29 + 102533 = 102562
- 59 + 102503 = 102562
- 101 + 102461 = 102562
- 233 + 102329 = 102562
- 263 + 102299 = 102562
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 102,562 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
