Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109478, here are decompositions:
- 7 + 109471 = 109478
- 37 + 109441 = 109478
- 157 + 109321 = 109478
- 181 + 109297 = 109478
- 199 + 109279 = 109478
- 211 + 109267 = 109478
- 277 + 109201 = 109478
- 307 + 109171 = 109478
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 109,478 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
