Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124420, here are decompositions:
- 53 + 124367 = 124420
- 71 + 124349 = 124420
- 83 + 124337 = 124420
- 173 + 124247 = 124420
- 227 + 124193 = 124420
- 239 + 124181 = 124420
- 281 + 124139 = 124420
- 353 + 124067 = 124420
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 124,420 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
