Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124040, here are decompositions:
- 19 + 124021 = 124040
- 43 + 123997 = 124040
- 61 + 123979 = 124040
- 67 + 123973 = 124040
- 109 + 123931 = 124040
- 211 + 123829 = 124040
- 223 + 123817 = 124040
- 283 + 123757 = 124040
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 124,040 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
