Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155024, here are decompositions:
- 7 + 155017 = 155024
- 43 + 154981 = 155024
- 97 + 154927 = 155024
- 127 + 154897 = 155024
- 151 + 154873 = 155024
- 271 + 154753 = 155024
- 277 + 154747 = 155024
- 433 + 154591 = 155024
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 155,024 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
