Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124208, here are decompositions:
- 37 + 124171 = 124208
- 61 + 124147 = 124208
- 211 + 123997 = 124208
- 229 + 123979 = 124208
- 277 + 123931 = 124208
- 379 + 123829 = 124208
- 421 + 123787 = 124208
- 541 + 123667 = 124208
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 124,208 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
