Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124790, here are decompositions:
- 7 + 124783 = 124790
- 13 + 124777 = 124790
- 19 + 124771 = 124790
- 31 + 124759 = 124790
- 37 + 124753 = 124790
- 73 + 124717 = 124790
- 97 + 124693 = 124790
- 157 + 124633 = 124790
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 124,790 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
