Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101128, here are decompositions:
- 11 + 101117 = 101128
- 17 + 101111 = 101128
- 47 + 101081 = 101128
- 101 + 101027 = 101128
- 107 + 101021 = 101128
- 191 + 100937 = 101128
- 197 + 100931 = 101128
- 281 + 100847 = 101128
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 101,128 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
