Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109154, here are decompositions:
- 7 + 109147 = 109154
- 13 + 109141 = 109154
- 43 + 109111 = 109154
- 163 + 108991 = 109154
- 193 + 108961 = 109154
- 211 + 108943 = 109154
- 271 + 108883 = 109154
- 277 + 108877 = 109154
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 109,154 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
