Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124142, here are decompositions:
- 3 + 124139 = 124142
- 19 + 124123 = 124142
- 163 + 123979 = 124142
- 211 + 123931 = 124142
- 313 + 123829 = 124142
- 409 + 123733 = 124142
- 523 + 123619 = 124142
- 541 + 123601 = 124142
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 124,142 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
