Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108778, here are decompositions:
- 17 + 108761 = 108778
- 71 + 108707 = 108778
- 101 + 108677 = 108778
- 191 + 108587 = 108778
- 281 + 108497 = 108778
- 317 + 108461 = 108778
- 401 + 108377 = 108778
- 419 + 108359 = 108778
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 108,778 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
