Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155324, here are decompositions:
- 7 + 155317 = 155324
- 73 + 155251 = 155324
- 157 + 155167 = 155324
- 163 + 155161 = 155324
- 241 + 155083 = 155324
- 277 + 155047 = 155324
- 307 + 155017 = 155324
- 397 + 154927 = 155324
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 155,324 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
