Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149078, here are decompositions:
- 19 + 149059 = 149078
- 67 + 149011 = 149078
- 151 + 148927 = 149078
- 157 + 148921 = 149078
- 211 + 148867 = 149078
- 331 + 148747 = 149078
- 367 + 148711 = 149078
- 409 + 148669 = 149078
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 149,078 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
