Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155152, here are decompositions:
- 71 + 155081 = 155152
- 83 + 155069 = 155152
- 149 + 155003 = 155152
- 269 + 154883 = 155152
- 281 + 154871 = 155152
- 311 + 154841 = 155152
- 353 + 154799 = 155152
- 383 + 154769 = 155152
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 155,152 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
