Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145006, here are decompositions:
- 23 + 144983 = 145006
- 89 + 144917 = 145006
- 107 + 144899 = 145006
- 167 + 144839 = 145006
- 227 + 144779 = 145006
- 233 + 144773 = 145006
- 269 + 144737 = 145006
- 347 + 144659 = 145006
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 145,006 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
