Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108780, here are decompositions:
- 11 + 108769 = 108780
- 19 + 108761 = 108780
- 29 + 108751 = 108780
- 41 + 108739 = 108780
- 53 + 108727 = 108780
- 71 + 108709 = 108780
- 73 + 108707 = 108780
- 103 + 108677 = 108780
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 108,780 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
