Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101078, here are decompositions:
- 79 + 100999 = 101078
- 97 + 100981 = 101078
- 151 + 100927 = 101078
- 277 + 100801 = 101078
- 331 + 100747 = 101078
- 337 + 100741 = 101078
- 379 + 100699 = 101078
- 409 + 100669 = 101078
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 101,078 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
