Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124642, here are decompositions:
- 41 + 124601 = 124642
- 101 + 124541 = 124642
- 113 + 124529 = 124642
- 149 + 124493 = 124642
- 293 + 124349 = 124642
- 443 + 124199 = 124642
- 449 + 124193 = 124642
- 461 + 124181 = 124642
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 124,642 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
