Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124340, here are decompositions:
- 3 + 124337 = 124340
- 31 + 124309 = 124340
- 37 + 124303 = 124340
- 43 + 124297 = 124340
- 109 + 124231 = 124340
- 127 + 124213 = 124340
- 157 + 124183 = 124340
- 193 + 124147 = 124340
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 124,340 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
