Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155264, here are decompositions:
- 13 + 155251 = 155264
- 61 + 155203 = 155264
- 73 + 155191 = 155264
- 97 + 155167 = 155264
- 103 + 155161 = 155264
- 127 + 155137 = 155264
- 181 + 155083 = 155264
- 283 + 154981 = 155264
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 155,264 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
