Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152000, here are decompositions:
- 31 + 151969 = 152000
- 61 + 151939 = 152000
- 97 + 151903 = 152000
- 103 + 151897 = 152000
- 151 + 151849 = 152000
- 229 + 151771 = 152000
- 271 + 151729 = 152000
- 283 + 151717 = 152000
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 152,000 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
