Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155084, here are decompositions:
- 3 + 155081 = 155084
- 37 + 155047 = 155084
- 67 + 155017 = 155084
- 103 + 154981 = 155084
- 151 + 154933 = 155084
- 157 + 154927 = 155084
- 211 + 154873 = 155084
- 277 + 154807 = 155084
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 155,084 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 155084 first appears in π at position 211,375 of the decimal expansion (the 211,375ordinal-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.
