Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124224, here are decompositions:
- 11 + 124213 = 124224
- 31 + 124193 = 124224
- 41 + 124183 = 124224
- 43 + 124181 = 124224
- 53 + 124171 = 124224
- 71 + 124153 = 124224
- 101 + 124123 = 124224
- 103 + 124121 = 124224
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 124,224 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
