Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145024, here are decompositions:
- 3 + 145021 = 145024
- 17 + 145007 = 145024
- 41 + 144983 = 145024
- 83 + 144941 = 145024
- 107 + 144917 = 145024
- 137 + 144887 = 145024
- 233 + 144791 = 145024
- 251 + 144773 = 145024
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 145,024 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
