Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102620, here are decompositions:
- 13 + 102607 = 102620
- 61 + 102559 = 102620
- 73 + 102547 = 102620
- 97 + 102523 = 102620
- 139 + 102481 = 102620
- 211 + 102409 = 102620
- 223 + 102397 = 102620
- 283 + 102337 = 102620
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 102,620 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
