Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145052, here are decompositions:
- 31 + 145021 = 145052
- 43 + 145009 = 145052
- 79 + 144973 = 145052
- 163 + 144889 = 145052
- 223 + 144829 = 145052
- 463 + 144589 = 145052
- 541 + 144511 = 145052
- 571 + 144481 = 145052
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 145,052 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
