Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145094, here are decompositions:
- 3 + 145091 = 145094
- 31 + 145063 = 145094
- 73 + 145021 = 145094
- 127 + 144967 = 145094
- 163 + 144931 = 145094
- 211 + 144883 = 145094
- 277 + 144817 = 145094
- 331 + 144763 = 145094
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 145,094 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
