Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103980, here are decompositions:
- 11 + 103969 = 103980
- 13 + 103967 = 103980
- 17 + 103963 = 103980
- 29 + 103951 = 103980
- 61 + 103919 = 103980
- 67 + 103913 = 103980
- 113 + 103867 = 103980
- 137 + 103843 = 103980
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 103 980 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
