Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155504, here are decompositions:
- 3 + 155501 = 155504
- 31 + 155473 = 155504
- 43 + 155461 = 155504
- 61 + 155443 = 155504
- 127 + 155377 = 155504
- 313 + 155191 = 155504
- 337 + 155167 = 155504
- 367 + 155137 = 155504
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 155,504 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
