Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 134978, here are decompositions:
- 31 + 134947 = 134978
- 61 + 134917 = 134978
- 127 + 134851 = 134978
- 139 + 134839 = 134978
- 271 + 134707 = 134978
- 397 + 134581 = 134978
- 541 + 134437 = 134978
- 577 + 134401 = 134978
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 134,978 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
