Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120028, here are decompositions:
- 11 + 120017 = 120028
- 17 + 120011 = 120028
- 47 + 119981 = 120028
- 107 + 119921 = 120028
- 137 + 119891 = 120028
- 179 + 119849 = 120028
- 197 + 119831 = 120028
- 257 + 119771 = 120028
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 120,028 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
