Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109128, here are decompositions:
- 7 + 109121 = 109128
- 17 + 109111 = 109128
- 31 + 109097 = 109128
- 79 + 109049 = 109128
- 127 + 109001 = 109128
- 137 + 108991 = 109128
- 157 + 108971 = 109128
- 167 + 108961 = 109128
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 109,128 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
