Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102340, here are decompositions:
- 3 + 102337 = 102340
- 11 + 102329 = 102340
- 23 + 102317 = 102340
- 41 + 102299 = 102340
- 47 + 102293 = 102340
- 89 + 102251 = 102340
- 107 + 102233 = 102340
- 137 + 102203 = 102340
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 102,340 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
