Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103078, here are decompositions:
- 11 + 103067 = 103078
- 29 + 103049 = 103078
- 71 + 103007 = 103078
- 149 + 102929 = 103078
- 167 + 102911 = 103078
- 197 + 102881 = 103078
- 281 + 102797 = 103078
- 317 + 102761 = 103078
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 103,078 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
