Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000128, here are decompositions:
- 7 + 1000121 = 1000128
- 11 + 1000117 = 1000128
- 29 + 1000099 = 1000128
- 47 + 1000081 = 1000128
- 89 + 1000039 = 1000128
- 149 + 999979 = 1000128
- 167 + 999961 = 1000128
- 197 + 999931 = 1000128
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 1,000,128 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
