Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145008, here are decompositions:
- 41 + 144967 = 145008
- 47 + 144961 = 145008
- 67 + 144941 = 145008
- 109 + 144899 = 145008
- 179 + 144829 = 145008
- 191 + 144817 = 145008
- 229 + 144779 = 145008
- 251 + 144757 = 145008
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 145,008 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
