Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124020, here are decompositions:
- 19 + 124001 = 124020
- 23 + 123997 = 124020
- 31 + 123989 = 124020
- 37 + 123983 = 124020
- 41 + 123979 = 124020
- 47 + 123973 = 124020
- 67 + 123953 = 124020
- 79 + 123941 = 124020
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 124,020 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
