Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155104, here are decompositions:
- 17 + 155087 = 155104
- 23 + 155081 = 155104
- 101 + 155003 = 155104
- 113 + 154991 = 155104
- 167 + 154937 = 155104
- 227 + 154877 = 155104
- 233 + 154871 = 155104
- 263 + 154841 = 155104
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 155,104 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 155104 first appears in π at position 502,115 of the decimal expansion (the 502,115ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
