Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145252, here are decompositions:
- 59 + 145193 = 145252
- 113 + 145139 = 145252
- 131 + 145121 = 145252
- 269 + 144983 = 145252
- 311 + 144941 = 145252
- 353 + 144899 = 145252
- 461 + 144791 = 145252
- 479 + 144773 = 145252
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 145,252 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
